However, there are concerns that the blue check verified service could lead to a two-tiered system on social media, where verified accounts have more privileges than unverified accounts. The platform will then verify this information and grant the blue checkmark badge to the user's profile. Users will have to provide their personal information, such as their name, date of birth, and a government-issued ID. Many businesses and advertisers prefer to work with verified accounts, as they are more reliable and have a higher reach.įacebook and Instagram have not revealed any details about how the blue check verified service will work, but it is expected to be a straightforward process. The service will enable them to prove their authenticity and build trust with their followers, which is crucial in the world of social media marketing. The blue check verified service will also help content creators, influencers, and celebrities to establish their brand and build their following. The blue checkmark is already available on Twitter, LinkedIn, and TikTok, and it is a highly coveted symbol of legitimacy among social media users. This badge is a sign of authenticity and credibility, indicating that the profile is not fake or impersonating someone else. It is an authentication service that confirms the identity of a user and gives them a blue checkmark badge on their profile. The blue check verified service is not new to social media platforms. To address this challenge, Facebook and Instagram have planned to introduce a blue check verified service for their users. However, the rise of fake news and misinformation has made it difficult to separate fact from fiction on these platforms. Social media platforms have become an essential part of our daily lives, where we share our thoughts, connect with our friends and family, and consume news and entertainment. Chiu 2 and Cedric Ho 3ĭepartment of Computer Science and Engineering, Hong Kong University of Science and Technology,ġ Dickson Computer Systems, Kowloon, Hong Kong watermarking is a promising technology to embed information as unperceivable signáis in digital contents.Facebook and Instagram's Blue Checkmark Badge to Verify Authenticity of User Accounts Various watermarking techniques have been proposed to protect copyrights of multimedia digital contents over Internet trading so that ownership of the contents can be determined in subsequent copyrights disputes.
However, their applications in preventing unauthorized distribution of intelligence document have not been studied. In this paper, we propose a watermark-based document distribution protocol, which complements conventional cryptography-based access control schemes, to address the problem of tracing unauthorized distribution of sensitive intelligence documents. The reinforcement of document distribution policies requires a concrete support of non-repudiation in the distribution process. The distribution protocol is adapted from our previous work on the watermarking infrastructure for enterprise document management. It makes use of intelligence user certificates to embed the identity of the users into the intelligence documents to whom are distributed. In particular, keeping the identity secrecy between document providers and users (but yet traceable upon disputes) is a key contribution of this protocol in order to support for intelligence applications. We also outline an implementation of the distribution protocol and watermarking scheme employed.

The enforcement of distribution policies for sensitive intelligence documents is important but difficult.
Sensitive documents may be found left behind in conference rooms, common áreas, printing rooms, or public folders.
Access control based on cryptography alone cannot address this problem. Once after obtaining access to a sensitive document may a person make unnecessary copies or handle it without care.
A major challenge in the reinforcement of distribution policies for sensitive documents is the support of non-repudiation in the underlying process so that unauthorized copies of intelligence documents can be identified and traced back to their users. The reinforcement should also be applicable to both hard copies and soft copies of the documents. Conventional cryptographic schemes that cover only soft copies are inadequate to handle this requirement.ĭigital watermarking is a promising technology employed by various digital rights management (DRM) systems to achieve rights management.
