A method and computer readable medium for exploring similar users and items of a media. service includes generating a user interface. The user interface displays a user selectable indicia representing a similar member function for allowing a user to search a media service for at least one other user. The one other user has a degree of similarity with respect to the searching user. Another method includes facilitating the search of such a similar user within a media service.

A method includes generating, by a computing device, a unique identifier (ID) based on copyright information associated with textual content, wherein the copyright information and the textual content are recorded on a blockchain of a blockchain network; identifying, by the computing device, one or more attributes associated with punctuation marks included in the textual content; and embedding, by the computing device, the unique ID in the textual content by changing the one or more attributes associated with the punctuation marks in a manner representative of the unique ID, wherein the embedding produces information-embedded text configured to enable retrieval of the copyright information from the blockchain based on the unique ID, and wherein visual difference between the textual content and the information-embedded text is not apparent to an unaided human eye.

This disclosure relates to, among other things, systems and methods for managing electronic content. Certain embodiments disclosed herein provide for a trusted data management platform that may interact with a trusted assertion service and/or a digital rights management service to manage access to and/or use of electronic content. Content creators and/or other content rights holder may register their content and/or associate rights using the trusted data management platform and/or a trusted assertion service and be assured that their content rights are securely managed and respected.

The invention described herein is directed to a secure text messaging and object sharing mobile application connected to a DRM cloud service that provides encryption, digital rights management (DRM) of the text and of the attachments, blockchain transactions, the capability of attaching documents, photos and so forth, the capability of interfacing with a user's contacts application, and that operates in both Android and iOS environments.

A user terminal generates a first key pair and a second key pair, transmits a permission request including a public encryption key of the second key pair after electronically signing the permission request with a secret encryption key, and acquires, from permission information transmitted from a right-holder terminal, a content decryption key by using a secret decryption key of the second key pair and uses the content. The right-holder terminal stores a third key pair and the content decryption key, verifies the permission request received, and encrypts the content decryption key by using the public encryption key of the second key pair included in the permission request and transmits the permission information including the encrypted content decryption key after electronically signing the permission information with a secret encryption key of the third key pair. The permission request and the permission information are transmitted and received via a blockchain.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for securely publishing and accessing a media's premium content. Methods include a media that comprises premium content encrypted with a first cryptographic key. The media also comprises data structures that include this key and the access entitlements. These data structures are encrypted using the key for each entity that can authorize user access to the media. Methods further include verifying user access to the media and then providing the decrypted premium content. Methods include decrypting the data structure using the authorizing entity's key and providing the first cryptographic key in the decrypted data structure to the client device, after verifying that the user has the appropriate access entitlements for the media. Methods include decrypting the premium content using the first cryptographic key and then displaying the media, including the decrypted premium content, on the client device.

Methods, computer program products, and systems are presented and can include for instance: crowdsourcing data from a plurality of users via a computer network, the data including feedback data regarding digital rights click through documents, wherein each of the users is a party to at least one of the digital rights click through documents; storing the data obtained by the crowdsourcing into a digital rights history repository; examining a digital rights click through document of a certain user, wherein the digital rights click through document controls access to a digital asset, wherein the examining includes using at least a portion of the feedback data of the digital rights history repository; and augmenting content of the digital rights click through document based on a result of the examining.

The invention relates generally to a system and method for implementing a multi-dealer market data distribution system with digital rights management. An embodiment of the present invention is directed to a Market Data Hub with Distributed Ledger Technology. The innovative system and method are directed to implementing a Quorum Blockchain Node that manages contributed content and allows for custom analytics, alerting, reporting, machine learning interfaces, etc., while preserving entitlements controls and privacy controls specific to participants.

In some examples, a system for server-side rendering of password-protected files can receive, from a client device, a request to view a file on the system, determine that the file should be converted to a different format prior to presentation at the client device, and determine that the file is a password-protected file. The system can send a response to the client device indicating the file is a password-protected file. In response to receiving the password from the client device, the system can generate, based on the password, a preview of the password-protected file including at least a portion of the password-protected file rendered in the different format. After generating the preview, the system can store an encrypted copy of the preview in storage for future requests, and send the preview to the client device.
