Latest Patents
One of Randy Langer's latest patents is a method and system for authorizing client devices to receive secured data streams. This system utilizes digital certificates embedded in client devices to ensure secure access to data. Each digital certificate is associated with a freely distributed cryptographically signed group file that contains an embedded expiration date. The group file can be linked to multiple digital certificates, but each certificate is tied to a single group file. The group file includes cryptographic keys that decrypt a section of the digital certificate, revealing a set of client keys. These client keys are then used to encrypt a program key, which is sent back to the client device. When a client device requests specific data, the system compares the issuance timestamp of the content to the expiration date in the group file. If the timestamp is after the expiration date, access is denied. If it is before the expiration date, the requested content is sent to the client device, encrypted with the program key.
