1. A computer-implemented method for detecting and using unique device identifiers to enhance security of access-right assignments, the method comprising: receiving a first communication from a first electronic device associated with a first user, the first communication corresponding to a first request to retrieve access data associated with the first user, the access data corresponding to one or more access rights; receiving a second communication from the first electronic device, the second communication including a second request for an access right; identifying first metadata associated with the second communication, the first metadata including one or more first composites; identifying a first composite of the one or more first composites included in the first metadata; identifying a first value corresponding to the first composite, the first value being representative of a first device identifier that uniquely identifies the first electronic device from amongst a plurality of electronic devices, the first device identifier including a first characteristic of the first electronic device; generating a first access code corresponding to the access right, at least a portion of the first access code including a representation of the first device identifier; receiving a third communication from the first electronic device, the third communication corresponding to a third request to transfer the access right to a second user; verifying that the third request to transfer the access right corresponds to the first electronic device associated with the first user; receiving a fourth communication from a second electronic device associated with the second user, the fourth communication corresponding to an indication to proceed with the transfer of the access right; identifying second metadata associated with the fourth communication, the second metadata including one or more second composites; identifying a second composite from the one or more second composites; identifying a second value corresponding to the second composite, the second value being representative of a second device identifier that uniquely identifies the second electronic device from amongst the plurality of electronic devices, the second device identifier including a second characteristic of the second electronic device; transforming the first access code corresponding to the access right into a second access code, at least a portion of the second access code including a representation of the second device identifier, transformation of the access right facilitating transfer of the access right to the second electronic device; and transmitting, to the second electronic device, a fifth communication that includes the second access code.
