Secure visual transactions for mobile devices

A system, comprising:

• one or more vision sensors to capture visual data associated with an environment;
• a display device;
• and
• one or more processing devices to:
• detect a user within a proximity of the display device, wherein the user is detected based on the visual data captured by the one or more vision sensors;
• identify a mobile transaction associated with the user, wherein the mobile transaction comprises a potential transaction to be completed using a mobile device of the user;
• access transaction data associated with the mobile transaction;
• encrypt the transaction data based on an encryption key associated with the user, wherein encrypting the transaction data causes encrypted transaction data to be generated;
• generate a visual code associated with the encrypted transaction data, wherein the visual code comprises visually encoded data, and wherein the visual code is generated within a protected execution environment of the one or more processing devices;
• establish a protected datapath between the one or more processing devices and the display device;
• and
• transmit the visual code to the display device via the protected datapath, wherein the visual code is to be displayed on the display device.

At least one machine accessible storage medium having instructions stored thereon, wherein the instructions, when executed on a machine, cause the machine to:

• detect a user within a proximity of a display device, wherein the user is detected based on visual data captured by one or more vision sensors;
• identify a mobile transaction associated with the user, wherein the mobile transaction comprises a potential transaction to be completed using a mobile device of the user;
• access transaction data associated with the mobile transaction;
• encrypt the transaction data based on an encryption key associated with the user, wherein encrypting the transaction data causes encrypted transaction data to be generated;
• generate a visual code associated with the encrypted transaction data, wherein the visual code comprises visually encoded data, and wherein the visual code is generated within a protected execution environment of a processor;
• establish a protected datapath between the processor and the display device;
• and
• transmit the visual code to the display device via the protected datapath, wherein the visual code is to be displayed on the display device.
