Delivery point validation system

A non-transitory computer-readable storage medium including program code, which, when executed by a processor, causes the processor to perform a method for processing data, the method comprising:

• receiving, by the computer, a data element including at least a name or an address;
• forming, by the computer utilizing a cryptographic procedure, a cryptographic value from the data element;
• extracting a plurality of samples from a binary representation of the cryptographic value, each of the each of the plurality of samples comprising one or more bits of said binary representation of the cryptographic value, the samples identifying one or more bits of previously stored data, the previously stored data representing a list of valid data elements and being formed by the cryptographic procedure from the list;
• querying whether the received data element is included in the list of the valid data elements;
• checking bit values of the bits of the previously stored data based on each of the plurality of bit samples;
• and
• determining, using the computer, whether the data element is included in the list based on a result of the checking.

A system for processing data comprising:

• a receiver that receives a data item comprising at least a name or an address;
• an encoder that forms, by utilizing a cryptographic procedure, a cryptographic value from the data element;
• an extraction circuit that extracts a plurality of samples from a binary representation of the cryptographic value, each of the plurality of samples comprising one or more bits of said binary representation of the cryptographic value, the samples identifying one or more bits within previously stored data, the previously stored data representing a list of valid data elements and being formed by the cryptographic procedure from the list;
• and
• a validation component that query whether the received data element is included in the list of the valid data elements, checks bit values of the bits of the previously stored data based on each of the plurality of bit samples, and determines whether the data element is included in the list based on a checking result.
