Abstract
Systems and methods for providing and validating a digital ticket are disclosed. In one implementation, a ticket validating device includes one or more processors configured to obtain a digital ticket, a ticket-server signature, and a device signature from a ticket holder's device. The digital ticket is obtained from a ticket server by the ticket holder's device, the ticket-server signature is generated based on the digital ticket using a private key associated with the ticket server, and the device signature is generated based on the digital ticket using a private key associated with the ticket holder's device. The one or more processors are further configured to validate the digital ticket. The validation of the digital ticket includes verifying the ticket-server signature using a public key corresponding to the private key associated with the ticket server, and verifying the device signature using a public key corresponding to the private key associated with the ticket holder's device. Moreover, the one or more processors are further configured to cause generation of an output based on a result of the validation of the digital ticket.
