One or more strong proofs are maintained as associated with an account of a user. In response to a request to change a security setting of the account, an attempt is made to confirm the request by using one of the one or more strong proofs to notify the user. The change is permitted if the request is confirmed via one or more of the strong proofs, and otherwise the change to the security setting of the account is kept unchanged.

Protecting account security settings using strong proofs

A method for deterministic file content generation of seed based files is comprised of extracting a seed value from a seeded file signature, passing the seed value to a seeded content generating function to produce a set of generated content, and appending the set of generated content to the seed file signature to produce a seed-based file. A delta offset may also be included in the seeded file signature, the delta offset indicating where modified content is to be substituted within the generated content.

Deterministic file content generation of seed-based files

An exemplary implementation of a security gateway for online console-based gaming operates as a gateway between a public network (e.g., the Internet), and a private network (e.g., an internal data center network). The security gateway allows secure communication channels to be established with game consoles via the public network, and allows secure communication between game consoles on the public network and service devices on the private network.

In accordance with one aspect, a client device is sent an indication of one or more types of information available for the client device. In response to the indication, a request is received from the client device to retrieve the information available for the client device. The information is identified and sent to the client device. In accordance with another aspect, one or more friends of the user are identified from persistent data, and a check made as to whether each of them is logged in to the system. For each of them that is logged in to the system, the user is subscribed to the friend's information and the friend is subscribed to the user's information. In accordance with another aspect, a user is allowed to be a friend of another user only if the other user is also a friend of the user.
