A method for detection and use of device identifiers to enhance the security of data transfers between electronic devices. A first electronic device can transmit access data to a second electronic device. The access data can be associated with a first access code that can be generated based at least in part on data representing a device identifier of the first electronic device. A device identifier can uniquely identify the first electronic device from a plurality of electronic devices. Transferring the access data can involve transforming the first access code into a second access code that can include data representing a device identifier associated with the second electronic device. Transforming the first access code into the second access code can facilitate access to a resource associated with the access data for a second user, but not for a first user.

A method and associated system for matching and delivering digital work metadata to one or more digital service providers including modifying one or more digital work metadata files, which includes removing non-critical data or segment-erroneous data or performing a language translation; reformatting the one or more digital work metadata files for compatibility with a transformer model-based AI matching operation; performing a block grouping operation on the one or more digital work metadata files, where data associated with the one or more digital work metadata files is grouped in blocks and analyzed for one or more pairs of data records; performing the transformer model-based AI matching operation to determine whether each pair of the one or more pairs of data records comprise a matching pair of data records; and transmitting output data from the transformer model-based artificial intelligence matching operation to the one or more digital service providers.
