Abstract
In a digital ticketing system, tickets are created in groups. All the digital tickets in a group share a common signature value, but each ticket in the group has a unique seed value, which may be a random number. The common signature value is derived from hashing all the seed values in the group and then digitally signing a combination of the hash values. In one example, the hash values are concatenated and encrypted with a private key to generate the common signature value. The system may be implemented and tickets exchanged using mobile devices, such as mobile telephones.
Claims20
A digital ticketing method comprising:
- generating at least two seed values;
- generating a hash value from each seed value;
- digitally signing a combination of the hash values to create a signature value;
- generating at least two tickets, wherein each ticket includes a seed value and the signature value;
- and
- generating a combination of the hash values, wherein the combination of the hash values is a concatenation of the n corresponding hash values.
A digital ticketing method comprising:
- generating at least two seed values;
- generating a hash value from each seed value;
- digitally signing a combination of the hash values to create a signature value;
- generating at least two tickets, wherein each ticket includes a seed value and the signature value,
- wherein generating at least two seed values comprises generating n seed values, with each seed value corresponding to a ticket;
- wherein generating a hash value comprises generating n corresponding hash values;
- wherein digitally signing a combination of the hash values includes digitally signing a combination of the n hash values;
- and
- wherein generating at least two tickets comprises generating n tickets, wherein each ticket includes the corresponding seed value, the hash values that do not correspond to the seed value, and the signature value.
A digital ticketing method comprising:
- generating at least two seed values;
- generating a hash value from each seed value;
- digitally signing a combination of the hash values to create a signature value;
- and
- generating at least two tickets, wherein each ticket includes a seed value and the signature value;
- wherein the information included in each digital ticket is such that no one digital ticket can be reconstructed from information in the remaining digital tickets.
A digital ticketing method comprising:
- generating at least two seed values;
- generating a hash value from each seed value;
- digitally signing a combination of the hash values to create a signature value;
- generating at least two tickets, wherein each ticket includes a seed value and the signature value, wherein the seed values are generated by a ticket originator;
- and,
- sending the seed values to a ticket distributor at a location remote from the ticket originator;
- wherein the ticket distributor digitally signs the combination of the hash values.
