Techniques are disclosed for managing encrypted data stored in one or more blocks of a first data structure. One embodiment presented herein includes a computer-implemented method, which includes retrieving the encrypted data from the one or more blocks. The method further includes placing the encrypted data in a container object. The method further includes applying an encryption technique to the container object to generate an encrypted container object and a key. The method further includes generating a second data structure. A first block of the second data structure may include either the encrypted container object or information related to the encrypted container object.

Re-encrypting data on a hash chain

The invention relates to a method for documenting subjects using hash chains. The method includes receiving a subject data write request including one or more subject attribute values, generating a fingerprint from a current last block of a hash chain, and generating a payload from the subject data, the payload including the one or more subject attribute values and one or more keys identifying the one or more subject attribute values. The method further includes appending a block to the hash chain. The appended block includes the payload and the fingerprint.

Method and system for secure digital documentation of subjects using hash chains

A method for loading objects from hash chains. A version chain of a class for a serialized object is located in an instance block of an instance chain. A class version of the serialized object is compared to a current version of the class. When the class version of the serialized object matches the current version of the class, a runtime object is loaded by deserializing the serialized object. When the class version of the serialized object does not match the current version of the class: one or more field values are extracted from the serialized object; a converter function is applied to the one or more field values to generate one or more converted field values; and a runtime object that matches the current version is loaded with the one or more converted field values.
