Abstract

A system for secure medical and dental record interchange comprises a provider system and a payer system. The provider system includes a digital imager, a processing unit, a data transmission/reception device, and a memory having a provider management unit and a security unit. For each image acquired from the digital imager, the provider management unit generates a unique image ID, and creates an image relation structure having a source indicator, a status indicator, and a copy-from indicator. The provider management unit organizes images into a message for transmission to a payer system. The security unit performs message encryption, image signature generation, and message signature generation. The payer system includes a processing unit, a data transmission/reception device, and a memory having a payer management unit and a security unit. The payer system'"'"'s security unit validates message signatures and image signatures received. The payer management unit generates a message rejection notification or a message acceptance notification. A method for provider-side secure medical and dental record interchange comprises the steps of: acquiring an image; generating a unique image ID and an image relation structure; maintaining a status indicator, a source indicator, and a copy-from indicator; generating an image signature; creating a message that includes the image; and generating a message signature. A method for payer-side secure medical and dental record interchange comprises the steps of: validating a message signature; validating an image signature; and selectively generating a message acceptance notification or a message rejection notification.
