Abstract
A secure and scalable data storage system that includes a server and a plurality of clients. The server maintains an access permission file that includes a file-group name, a plurality of client access blocks, a first and second public key, and a signature that is based on a first private key. The signature ensures that only clients who have a certain level of access can modify the contents of the access blocks. Each client access block includes at least one of a first access key, a second access key and a third access key. The access keys are encapsulated within biometric information of the client. The server grants one of a first level of access based on a successful verification of a signed request with the first public key and a second level of access based on a successful verification of the signed request with the second public key.
