Abstract

In a method for mobile printing, a mobile device generates a symmetrical pair of encryption keys and transmits the first encryption key and a print request to an imaging device. When the mobile device receives a request from the imaging device for the second encryption key, the mobile device transmits the second encryption key to the imaging device. The imaging device then uses the second encryption key to decrypt encrypted rendered content and prints the content.

Claims

1. A method, comprising:

a mobile device transmitting a print request to an imaging device, the print request including a reference to content to be printed but not the content to be printed, a public key, and an address for the mobile device;

the imaging device transmitting the print request to a print service;

the print service receiving the print request from the imaging device;

in response to receiving the print request, the print service encrypting the content to be printed referenced in the print request using the public key;

the print service transmitting the encrypted content to the imaging device;

the imaging device requesting a private key corresponding to the public key from the mobile device at the address for the mobile device included in the print request;

the mobile device sending the imaging device the private key; and

the imaging device decrypting the encrypted content using the private key and printing the decrypted content.

2. The method of claim 1, wherein the print request includes a location of the content to be printed and the method further comprising the print service retrieving the content to be printed from the location included in the print request.

3. One or more non-transitory computer readable media having computer readable instructions thereon for:

a mobile device transmitting a print request to an imaging device, the print request including a reference to content to be printed but not the content to be printed, a public key, and an address for the mobile device;

the imaging device transmitting the print request to a print service;

the print service receiving the print request from the imaging device;

in response to receiving the print request, the print service encrypting the content to be printed referenced in the print request using the public key;

the print service transmitting the encrypted content to the imaging device;

the imaging device requesting a private key corresponding to the public key from the mobile device at the address for the mobile device included in the print request;

the mobile device sending the imaging device the private key; and

the imaging device decrypting the encrypted content using the private key and printing the decrypted content.

4. The one or more computer readable media of claim 3, wherein the print request includes a location of the content to be printed and the instructions further comprise instructions for the print service retrieving the content to be printed from the location included in the print request.
