A system and method are disclosed for controlling metadata associated with content on an electronic device that includes displaying interface screens for user entry of metadata control instructions, accepting user instructions, modifying metadata of applicable content, and associating the modified metadata with the applicable content. The system can export and/or store the applicable content along with modified metadata. The system can automatically modify metadata according to one or more profiles. Relevant profiles can be determined based on the export mechanism, destination or type of content. The system can add watermarks to indicate metadata modification. The system can display metadata for user modification. The content can include photos, videos or other content. The system can display metadata and geolocation indicators for each content item that indicate whether that item has associated metadata and geolocation information. The user can selectively modify metadata of selected content.

Methods, systems, and devices that support determining whether media data has been altered are described. Captured media data may be segmented into one or more subsets, and cryptographic representations (e.g., hashes) based on the subsets may be written to an immutable ledger, possibly along with metadata and other related data. A block of a blockchain may be created for each entry in the immutable ledger. A set of media data may be validated, if a corresponding immutable ledger exists, based on segmenting the set of media data into one or more subsets in accordance with the segmenting upon capture, creating candidate cryptographic representations (e.g., hashes) based on the subsets, and comparing the candidate cryptographic representations with contents of the corresponding immutable ledger.

A method of governing content presentation of multi-page electronic documents includes providing, to a publisher, a document file, which includes a program file, and a text file functionally associated with the program file. The publisher provides the text file to an author, who creates a version of a work of content based on the text file that is parsed into defined units of content. The author provides the units of content of the current version of the work of content to a user, to be viewed by the user on a display device in a sequence determined by the author. Creating the at least one version of the work of content includes enabling a primary secondary action key such that actuation, by the user, of the primary secondary action key advances a reading frame viewable by the user by a number of strings between main pages, plus one.

The exemplary embodiments are related to a device, a system, and a method for implementing a mechanism that is configured to prevent the unauthorized execution of software. A user device is configured to execute a feature access function corresponding to an application feature included in an application. The feature access function is configured to receive one of a plurality of values each time the application is launched. During operation, the feature access function receives a value and determines whether a condition is satisfied. When the condition is satisfied, the value is returned which indicates that execution of the application feature is permitted.

A method for hiding information in executable code comprising: identifying a set of pairs of interchangeable instructions, wherein each pair has an instruction order of execution that is reversible without changing a functionality of the executable code; organizing the pairs into a plurality of matrices based on a set of random seeds; for each matrix, inverting a submatrix consisting of a subset of columns from each matrix to identify a subset of pairs; identifying a matrix that has full column rank on a subset of columns that is a function of the pairs' location; storing an index of the identified matrix's associated seed in a secure data storage location; and encoding data into the executable code by reversing the order of execution of the subset of pairs and treating each pair having reversed instructions as a “1” and each pair of non-reversed instructions as a “0” or vice versa.

Methods and systems for removing sensitive information from a digital image. An instruction to share a digital image is received. It is then determined that the digital image contains a depiction of a corporate display medium that is classified as sensitive based on a policy and, based on the determination that the digital image contains the depiction of the corporate display medium that is classified as sensitive based on the policy, the digital image is processed to modify the depiction. The digital image is shared.

Disclosed are systems and methods for improving interactions with and between computers in content providing, generating, securing and/or hosting systems supported by or configured with personal computing devices, servers and/or platforms. The systems interact to identify and retrieve data within or across platforms, which can be used to improve the security and quality of data used in processing interactions between or among processors in such systems. The disclosed systems and methods provide added security features and functionality to media files through computerized, automated encoding and decoding of portions of media file content such that identified portions of the content are obfuscated upon display and communication to other users. The disclosed systems and methods provide a novel, computerized security feature(s) that protects data of media files from unintended exposure to third parties. The disclosed security features automatically prevent personal and/or private information from unwanted viewing and access from unauthenticated users.

Methods and systems for performing real time digital content concealment are described herein. A computing device may, in response to detecting a user within view of an image capture device of a client device, perform a first type of text recognition on a first region of digital content and a second type of text recognition on a second region of the digital content, where the first type of text recognition is determined based on a first type of content items contained in the first region and the second type of text recognition is determined based on a second type of content items contained in the second region. Based at least in part on rules corresponding to the user, the computing device may determine content items within the digital content to be concealed, and may modify the digital content to conceal the content items.

There is provided a computer-implemented method of enhancing data privacy. One or more tensors of numeric data are determined, at a processor, in dependence on input data. A transform is determined in dependence on user-associated data, which may be user input or biometric data. Each of the one or more tensors of numeric data are transformed into at least two fragments of data by applying the transform. Each of the fragments of data obfuscates the numeric data. Each of the at least two fragments of data are stored separately at a respective geographically separated storage system.

Some embodiments are directed to a compiler device (400) arranged for obfuscation of a computer program. The compiler device performs a live variable analysis on the computer program representation, and modifies the computer program representation to encode a first variable using at least a second variable as an encoding parameter.
