Some of this is due to the breakneck speed of how social media operates but it also has to do with how good these \u201cfakes\u201d really are. To the naked eye synthetic media is almost indiscernible. Ironically, AI itself \u2013 the very technology that is making it easier to manipulate media \u2013 won\u2019t be able to detect it either \u2013 casting a shadow of doubt on the legitimacy of what we see or hear.<\/p>\n\n\n\n<p>One promising direction is to provide viewers with reliable information about the source or&nbsp;<em>provenance<\/em>&nbsp;of a media object through a verifiable and trustworthy media authentication service. Project Origin has been created for this effort: an alliance of leading organizations from the publishing and technology worlds working together to create a process where the provenance and technical integrity of content can be confirmed. Establishing a chain of trust from the publisher to the consumer. This would allow consumers to make informed decisions about a media object\u2019s trustworthiness. For example, knowing the source of a news item lets a consumer know that the work meets the publisher\u2019s editorial standards.<\/p>\n\n\n\n<div style=\"padding-bottom:0; padding-top:0\" class=\"wp-block-msr-immersive-section alignfull row wp-block-msr-immersive-section\">\n\t\n\t<div class=\"container\">\n\t\t<div class=\"wp-block-msr-immersive-section__wrapper\">\n\t\t\t<div class=\"wp-block-media-text has-vertical-margin-none  has-vertical-padding-none  is-stacked-on-mobile\" style=\"grid-template-columns:20% auto\" data-bi-an=\"media-text\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"239\" height=\"256\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/amp-illustration.89f933d9.png\" alt=\"Origin AMP illustration\" class=\"wp-image-877410 size-full\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/amp-illustration.89f933d9.png 239w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/amp-illustration.89f933d9-168x180.png 168w\" sizes=\"(max-width: 239px) 100vw, 239px\" \/><\/figure><div class=\"wp-block-media-text__content\" data-bi-an=\"media-text\">\n<h2 id=\"this-is-technically-possible-through-a-system-called-authentication-of-media-via-provenance-amp\" class=\"has-text-align-right\">This is technically possible through a system called Authentication of Media via Provenance (AMP).<\/h2>\n\n\n\n<p class=\"has-text-align-right\">AMP allows media publishers to certify content at the time of capture or publication.

However, increasingly, media is shared on social media, and these platforms and services transform and optimize the media to support differing device, screen, and network conditions. For example, video can be encoded for a range of screen sizes and resolutions, and a variety of network conditions. In this case, the transformed video must be re-authenticated \u2013 either by the original publisher, or by the social media platform.<\/p>\t\t<\/div>\n\t<\/div>\n\n\t<\/div>\n\n\n\n<div style=\"padding-bottom:32px; padding-top:32px\" class=\"wp-block-msr-immersive-section alignfull row has-background has-dark-gray-background-color has-text-color has-white-color wp-block-msr-immersive-section\">\n\t\n\t<div class=\"container\">\n\t\t<div class=\"wp-block-msr-immersive-section__wrapper col-lg-11 col-xl-9 px-0 m-auto\">\n\t\t\t<h2 id=\"amp-manifests\">AMP manifests<\/h2>\n\n\n\n<p>The manifest is the central data structure in AMP.

These tools range from a camera app on a cellphone, to sophisticated image and video editing apps. An individual might then share the media objects using a social media app or services; a news organization might use Azure Media Services to process the video for publication on the web. Existing tools allow people and organizations to add tags and other metadata but resulting media tags and objects can easily be changed in misleading ways.<\/p>\n\n\n\n<p>Future tools will be enhanced with AMP technology to use create cryptographically protected manifests for media objects and their tags so that users know exactly where media comes from and who processed it. Note that AMP does not&nbsp;<em>stop<\/em>&nbsp;people changing the tags or imagery, but it does let consumers know that changes have been made.<\/p>\n\n\n\n<h2 id=\"amp-clients\">AMP clients<\/h2>\n\n\n\n<p>People view media using web sites and apps. AMP-enhanced players and services will compare media object with the associated manifests to see if the video is unchanged. If the manifest is properly signed, and the video fingerprints in the manifest match the video being played, then the publisher and tags will be displayed (perhaps behind an \u201cinfo\u201d button or icon.) If the video does not match the manifest or the signature is invalid a warning may be given.<\/p>\n\n\n\n<p>It will take time before the majority of Internet media is protected using AMP, but we hope that journalists and news organizations will take the lead towards increasing the trustworthiness of media on the web.<\/p>\t\t<\/div>\n\t<\/div>\n\n\t<\/div>\n\n\n\n<div style=\"padding-bottom:32px; padding-top:32px\" class=\"wp-block-msr-immersive-section alignfull row wp-block-msr-immersive-section\">\n\t\n\t<div class=\"container\">\n\t\t<div class=\"wp-block-msr-immersive-section__wrapper\">\n\t\t\t<h2 id=\"anatomy-of-the-amp-manifest\">Anatomy of the AMP manifest<\/h2>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-4 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:80%\">\n<p><strong>Media binding<\/strong><\/p>\n\n\n\n<p>In addition to metadata, AMP manifests authenticate media objects; we call this&nbsp;<em>media binding<\/em>. AMP supports a variety of ways to authenticate media.<\/p>\n\n\n\n<p>The simplest technique uses cryptographic hashing: a technique for producing a short \u201cfingerprint\u201d for a document, with the characteristic that it is extremely unlikely that any other document hashes to the same value. With it, even the tiniest change to a media will result in a different fingerprint: this is good &#8211; because impossible for an attacker to create content that matches the manifest but is not the original \u2013 but also bad \u2013 because transformations like recompressing without changing the meaning or appearance will break the binding between the content and the manifest. An alternative to cryptographic hashing is called soft hashing: a fingerprint for a media object that survives modest changes \u2013 like recompression.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"195\" height=\"195\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-fingerprint-icon.png\" alt=\"AMP manifest fingerprint icon\" class=\"wp-image-877479\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-fingerprint-icon.png 195w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-fingerprint-icon-150x150.png 150w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-fingerprint-icon-180x180.png 180w\" sizes=\"(max-width: 195px) 100vw, 195px\" \/><\/figure>\n<\/div>\n<\/div>\t\t<\/div>\n\t<\/div>\n\n\t<\/div>\n\n\n\n<div style=\"padding-bottom:32px; padding-top:32px\" class=\"wp-block-msr-immersive-section alignfull row wp-block-msr-immersive-section\">\n\t\n\t<div class=\"container\">\n\t\t<div class=\"wp-block-msr-immersive-section__wrapper\">\n\t\t\t<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-5 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"195\" height=\"195\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-download-icon.png\" alt=\"AMP manifest download icon\" class=\"wp-image-877476\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-download-icon.png 195w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-download-icon-150x150.png 150w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-download-icon-180x180.png 180w\" sizes=\"(max-width: 195px) 100vw, 195px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:80%\">\n<p><strong>AMP manifests and streaming media<\/strong><\/p>\n\n\n\n<p>In the past, media files had to be downloaded in their entirety before they could be played. Modern video delivery is far more sophisticated: modern video codecs and players start after a few seconds of download \u2013 the user does not wait for the entire file download before playing it.<\/p>\n\n\n\n<p>AMP supports streaming authentication to complement streaming delivery and playback. In addition to the manifest containing the hash of the entire video file, it also includes an array of hashes of short segments. Different codecs and network transport layers are best served by different chunking schemes, but all chunking schemes allow authentication to begin after a few seconds of video has been downloaded.<\/p>\n<\/div>\n<\/div>\t\t<\/div>\n\t<\/div>\n\n\t<\/div>\n\n\n\n<div style=\"padding-bottom:32px; padding-top:32px\" class=\"wp-block-msr-immersive-section alignfull row wp-block-msr-immersive-section\">\n\t\n\t<div class=\"container\">\n\t\t<div class=\"wp-block-msr-immersive-section__wrapper\">\n\t\t\t<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-6 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:80%\">\n<p><strong>Adaptive bit rate video<\/strong><\/p>\n\n\n\n<p>Another innovation in modern video delivery is called Adaptive Bitrate Streaming (ABR) \u2013 for example, MPEG-DASH. ABR lets a publisher or platform create a set of video files optimized for different players, screen sizes\/resolutions, and network conditions. For example, a publisher can create a video to be played on a 4K connected TV, and another version for a mobile device on cellular network. Smart web pages and apps can pick the stream that matches the screen and current network conditions and can even dynamically switch between streams as network conditions change.<\/p>\n\n\n\n<p>AMP supports ABR very similarly to the JPG image facsimiles introduced earlier. Each video is treated as a facsimile of the original, and the manifest contains bindings (chunk-hashes) for all versions of the video produced by the publisher.<\/p>\n\n\n\n<p>We use the term&nbsp;<em>facsimile&nbsp;to describe a video (or image) that is a simple re-encoding of an original. An AMP manifest can authenticate any number of facsimiles of a video that the publisher deems equivalent.<\/em><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"195\" height=\"195\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-video-icon.png\" alt=\"AMP manifest video bit rate icon\" class=\"wp-image-877482\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-video-icon.png 195w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-video-icon-150x150.png 150w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-video-icon-180x180.png 180w\" sizes=\"(max-width: 195px) 100vw, 195px\" \/><\/figure>\n<\/div>\n<\/div>\t\t<\/div>\n\t<\/div>\n\n\t<\/div>\n\n\n\n<div style=\"padding-bottom:32px; padding-top:32px\" class=\"wp-block-msr-immersive-section alignfull row wp-block-msr-immersive-section\">\n\t\n\t<div class=\"container\">\n\t\t<div class=\"wp-block-msr-immersive-section__wrapper\">\n\t\t\t<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"195\" height=\"195\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-cut-icon.png\" alt=\"AMP manifest media trim icon\" class=\"wp-image-877473\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-cut-icon.png 195w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-cut-icon-150x150.png 150w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/AMP-manifest-cut-icon-180x180.png 180w\" sizes=\"(max-width: 195px) 100vw, 195px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:80%\">\n<p><strong>AMP and derived works<\/strong><\/p>\n\n\n\n<p>In some cases, the media being authenticated is original.

Thus, we are forming a partnership with media organizations and additional technology providers. We plan to put this collaboration on a formal footing with the formation of an industry alliance similar to the Alliance for Open Media. Other companies can join, either as active contributors or supporters. A key goal of such an effort should be to promote the development of an open standard, to motivate fast adoption.<\/p>\n\n\n\n<p>The implementation of an AMP system can be a significant step in increasing trust in media, while protecting viewers and publisher.<\/p>\n<\/div><\/div>\t\t<\/div>\n\t<\/div>\n\n\t<img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"167\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/dark-banded-background.png\" class=\"wp-block-msr-immersive-section__background-image\" alt=\"dark black brown banded background strip\" style=\"object-position: 10% 10%\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/dark-banded-background.png 1920w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/dark-banded-background-300x31.png 300w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/dark-banded-background-1024x107.png 1024w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/dark-banded-background-768x80.png 768w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/dark-banded-background-1536x160.png 1536w, https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2022\/09\/dark-banded-background-240x25.png 240w\" sizes=\"(max-width: 1600px) 100vw, 1600px\" \/><\/div>\n\n\n","protected":false},"excerpt":{"rendered":"<p>Project Origin aims to create a measure of accountability through provenance.
