  • Manipulation-proof storage of evidence-relevant data
    Patent number: 11126750
    Abstract: A method for manipulation-proof storage of payload data is provided, including: storing the payload data in a chain of data records; forming, for each data record in the chain, a current hash value at least using the payload data comprised and stored in the respective data record; storing, in the data record, a predecessor hash value that corresponds to a hash value of a preceding data record, such that in a first data record in the chain, a predetermined root hash value replaces the predecessor hash value; storing, in a persistent memory, a chain of hash values including the current hash value, the predecessor hash value, and the predetermined root hash value, such that content, once stored in the persistent memory, is no longer modifiable or removable from the persistent memory; and storing the data records in a reversible memory that is distinct from the persistent memory.
