Conventional storage technologies do not always give sufficient guarantees of security for critical information. Databases and file servers are regularly compromised, with consequential theft of identities and unauthorized use of sensitive information. Some cryptographic technologies increase the security guarantees, but rely on a key, and key secrecy and maintenance are difficult problems. Meanwhile, there is an accelerating trend of moving data from local storage to Internet storage. As a result, automatic security of critical information without the need for key management promises to be an important technology for Web Applications. This thesis presents such solution for Internet data storage that uses a secret sharing scheme. The shared secrets are packaged as JSON objects and delivered to various endpoints using HTTP semantics. A shopping website is developed to demonstrate the solution.
