Continuous authentication for a real time hologram

A computer program product, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to perform operations for:

• receiving a request and a hologram, wherein the hologram is embedded with a first key phrase in accordance with a first sequence, and wherein the first sequence indicates which portions of the first key phrase are embedded in specific locations of the hologram;
• retrieving a first seed and a second seed;
• generating a second key phrase using the first seed;
• generating a second sequence using the second seed;
• determining whether portions of the second key phrase are embedded in specific locations of the hologram in accordance with the second sequence;
• in response to determining that the portions of the second key phrase are embedded in specific locations of the hologram in accordance with the second sequence,
• displaying the hologram;
• and
• processing the request;
• and
• in response to determining that the portions of the second key phrase are not embedded in specific locations of the hologram in accordance with the second sequence, rejecting the request.

A computer system, comprising:

• one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices;
• and
• program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to perform operations comprising:
• receiving a request and a hologram, wherein the hologram is embedded with a first key phrase in accordance with a first sequence, and wherein the first sequence indicates which portions of the first key phrase are embedded in specific locations of the hologram;
• retrieving a first seed and a second seed;
• generating a second key phrase using the first seed;
• generating a second sequence using the second seed;
• determining whether portions of the second key phrase are embedded in specific locations of the hologram in accordance with the second sequence;
• in response to determining that the portions of the second key phrase are embedded in specific locations of the hologram in accordance with the second sequence,
• displaying the hologram;
• and
• processing the request;
• and
• in response to determining that the portions of the second key phrase are not embedded in specific locations of the hologram in accordance with the second sequence, rejecting the request.
