Record addressing information retrieval based on user data descriptors
View Patent ↗Record addressing information retrieval is achieved using a plurality of user data descriptors. When a threshold number of user data descriptors from a set of user data descriptors are received, the threshold number of user data descriptors can be converted into a computed record index that is compared to a list of record indexes associated with a plurality of records. When the computed record index compares favorably to a record index in the list of record indexes, the record addressing information for a particular record is retrieved based on the record index.

converting, by the processing module, the threshold number of user data descriptors into a computed record index;
comparing, by the processing module, the computed record index to a list of record indexes associated with a plurality of records; and
