DATA TRUNCATION FROM CRYPTOGRAPHIC DATA STRUCTURES

Resumen de: US20260089008A1

Methods for asynchronously determining relational data integrity using cryptographic data structures are performed by systems and devices. Changes in current tables of relational databases are reflected in associated history tables. Cryptographic hybrid blockchain ledgers are updated with transaction records, for entry changes in current and history tables, including transaction information and hash values of corresponding entry changes. Hybrid blockchain ledgers also include root hash values of Merkle trees of transaction records in current blocks, and hash values of prior blocks. A current block receipt is asynchronously generated and provided as a single hash value from which the validity states of the tables and ledger are able to be verified. Cryptographic receipts of specific transactions reflected in table entry changes are generated and provide immutable evidence of specific transaction existence for users. Ledger-enabled tables are provided for mixed database operations with ledger-disabled tables, and temporal history table database operations are enabled.

Resumen de: US20260082228A1

In various embodiments, systems and methods for ledger-based cookie management are provided. Rather than store cookie data as text files on the local device drive, cookie data is recorded to a blockchain technology cookie ledger store on a network resource.

The cookie gateway may verify authenticity of the user and generate a cookie access token that it transmits to the cloud-based service. The cloud-based service may use the cookie access token to locate the cookie ledger and access one or more records storing cookie data used by the cloud-based service. The cookie access token may expire upon termination of the session between the user equipment and the cloud-based service.
