Cloaking is a search engine optimization (SEO) technique in which the content presented to the search engine spider is different from that presented to the user's browser. This is done by delivering content based on the IP addresses or the User-Agent HTTP header of the user requesting the page. When a user is identified as a search engine spider, a server-side script delivers a different version of the web page, one that contains content not present on the visible page, or that is present but not searchable. The purpose of cloaking is sometimes to deceive search engines so they display the page when it would not otherwise be displayed (black hat SEO). However, it can also be a functional (though antiquated) technique for informing search engines of content they would not otherwise be able to locate because it is embedded in non-textual containers such as video or certain Adobe Flash components. Since 2006, better methods of accessibility, including progressive enhancement, have been available, so cloaking is no longer necessary for regular SEO.
A privacy data hierarchical cloaking and content filtering method in railway communication
This invention relates to the intersection of railway information security and multimedia processing, specifically a method for graded masking and content filtering of privacy data in railway communications. By configuring multi-level user permission rules, it applies varying degrees of privacy processing to keyframe images output by sensitive target detection targets. This allows for accurate identification of sensitive targets and masking only them to preserve background information. The masking intensity is dynamically adjusted based on user permissions, achieving effective voice desensitization and accurate keyword detection. Simultaneously, it establishes a comprehensive operation log and reverse audit closed loop. The advantages of this invention are: achieving a balance between information preservation and accurate masking; a role-based dynamic masking mechanism that meets the information detail requirements of different users, significantly improving flexibility compared to static masking techniques; high comprehensiveness of voice processing; a reliable audit closed loop ensuring traceability of operations and controllability of decryption; and wide applicability, suitable for railway communication scenarios in various fields such as government affairs and emergency response.

Secure cloaking of data
ActiveUS12596820B2Digital data protectionInternal/peripheral component protectionAlgorithmEngineering
In a method for providing secure data storage, a user selection of a plurality of cloaking sequences is received. The cloaking sequences include at least a first and second cloaking sequence. The method also includes cloaking data (e.g., one or more files). Cloaking the data includes retrieving a first hidden sequence associated with the first cloaking sequence, and retrieving a second hidden sequence associated with the second cloaking sequence. The second hidden sequence includes an ordered sequence of bit sets each including one or more bits. Cloaking the data also includes using the first hidden sequence to identify offset positions within the data, and using the ordered sequence of bit sets to perform one or more operations on the data at the identified offset positions. The method further includes storing the cloaked data.
