Claim 6:
7. A computer system for securing visible data, comprising:
one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage media, and program instructions stored on at least one of the one or more computer-readable tangible storage media for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
encrypting an on-screen data for viewing by a primary user, wherein the encrypted on-screen data is rendered on a display of an endpoint device of the primary user based on a security policy set by the primary user;
identifying a second external decryption device within a periphery defined by the endpoint device based on the security policy set by the primary user, wherein the identified second external decryption device is associated with a secondary user;
transmitting a challenge to the identified second external decryption device including a request for a passphrase generated by the primary user of the endpoint device; and
authenticating the identified second external decryption device based on receiving a response from the identified second external decryption device including the passphrase generated by the primary user of the endpoint device; and
decrypting the encrypted on-screen data for viewing by the secondary user using the authenticated identified second external decryption device.
