Abstract
A security method that includes determining a sensitivity value for content to be projected onto a holographic surface, and determining identity for people that are within visual range of the holographic surface. The method further includes determining which of the people is authorized to view the content being projected onto the holographic surface according to the sensitivity level. The holographic surface is shaped to provide a reshaped holographic surface that obstructs people that are not authorized to view the sensitivity level of the content. The content is then projected onto the reshaped holographic surface within vision of people authorized to view the sensitivity level of the content.
Claims18
A security method comprising:
- determining a sensitivity value for the content to be projected onto a holographic surface, the sensitivity value being related to sensitivity of the content;
- determining an identity for people within visual range of the holographic surface;
- determining by computer implemented method which of the people are authorized to view the content being projected onto the holographic surface according to the sensitivity level;
- shaping the holographic surface to provide a reshaped holographic surface that obstructs people that are not authorized to view the sensitivity level of the content;
- and
- projecting the content onto the reshaped holographic surface using a projector within vision of people authorized to view the sensitivity level of the content, wherein shaping the holographic surface to provide the reshaped holographic surface comprises increasing a thickness of the holographic surface to not be transparent to the people that are not authorized to view the sensitivity level of the content.
A system comprising:
- a memory;
- a hardware processor coupled to the memory;
- a sensitivity assignment application including instructions on said memory executed by the hardware processor for determining a sensitivity value for the content to be projected onto a holographic surface;
- a content to people calculator for determining which of the people that are within visual range of the holographic surface is authorized to view the content being projected onto the holographic surface according to the sensitivity level;
- an image shaping device for shaping the holographic surface to provide a reshaped holographic surface that obstructs people that are not authorized to view the sensitivity level of the content;
- and
- at least one projector for producing the reshaped holographic surface that obstructs people that are not authorized to view the sensitivity level of the content, and for projecting the content onto the reshaped holographic surface within vision of people authorized to view the sensitivity level of the content, wherein said producing the reshaped holographic surface comprises increasing a thickness of the holographic surface to not be transparent to the people that are not authorized to view the sensitivity level of the content.
A computer program product for performing a security method comprising a computer readable storage medium having computer readable program code embodied therein, the computer readable program code executable by a processor to cause the processor to:
- determine, using the processor, a sensitivity value for the content to be projected onto a holographic surface;
- determine, using the processor, identity for people that are within visual range of the holographic surface;
- determine, using the processor, which of the people is authorized to view the content being projected onto the holographic surface according to the sensitivity level;
- shape, using the processor, the holographic surface to provide a reshaped holographic surface that obstructs people that are not authorized to view the sensitivity level of the content;
- and
- project, using the processor, the content onto the reshaped holographic surface within vision of people authorized to view the sensitivity level of the content, wherein shaping the holographic surface to provide the reshaped holographic surface comprises increasing a thickness of the holographic surface to not be transparent to the people that are not authorized to view the sensitivity level of the content.
