A storage service receives a binary large object (blob) for storage, and the service creates first and second sets of data chunks from the blob. The chunks in the first set together equal the blob, and the service uses one or more encryption keys to encrypt each of the data chunks in the first set. The chunks in the second set also together equal the blob. The service assigns a message authentication code (MAC) to each data chunk in the second set. The service stores the encrypted data chunks in one or more data stores, and it stores the encryption keys and the MACs as metadata in a metadata memory.

Methods and systems for storage of large data objects

A method for brokering of know-how in various formats between users on an electronic Web service platform includes: allowing users access to the electronic Web service platform, requesting registration data from a user on the platform, managing interest area categories, receiving user offers for know-how in at least one interest area category, enabling searches of users for know-how in at least one interest area category, calculating and displaying a rating in respect of offers in at least one interest area category, approving to a selected offer an agreed exchange of know-how and a corresponding transfer of credit points, conveying selected know-how from the provider to the consumer and booking a corresponding transfer of credit points, and accepting and storing a rating given to the provider by the consumer in respect of the transferred know-how, wherein the rating is assigned to the interest area category of the transferred know-how.
