The user of the VR/AR technology may have protected content in a field of view of the user. Encrypted content is mapped to one or more protected surfaces on a display device. Contents mapped to a protected surface may be rendered on the display device but prevented from being replicated from the display device. ## Claims ### Claim 1 A method for displaying content components on a display device, the method comprising: receiving, by a processing platform, a plurality of content components; identifying, by the processing platform, an encrypted content component among the plurality of content components; and transmitting, by the processing platform, the encrypted content component to the display device, wherein at least the encrypted content component is mapped to a protected surface. ### Claim 2 (depends on 1) The method of claim 1, further comprising: identifying, by the processing platform, an unencrypted content component among the plurality of content components; and merging, by the processing platform, the encrypted content component and the unencrypted content component into a single output frame; and transmitting, by the processing platform, the single output frame to the display device, wherein the single output frame is mapped to one or more protected surfaces on the display device. ### Claim 3 (depends on 1) The method of claim 1, further comprising: generating the protected surface, wherein the encrypted content component is configured to be rendered only on the protected surface; and transmitting the protected surface to the display device, wherein the encrypted content component is rendered on the protected surface on the display device. ### Claim 4 (depends on 1) The method of claim 1, further comprising: upon receiving the plurality of content components, creating a plurality of frame loops, wherein each frame loop corresponds to one of the plurality of content components; queuing the plurality of frame loops into a frame loop pipeline; obtaining a frame loop from the frame loop pipeline; and determining whether the frame loop corresponds to the encrypted content component or an unencrypted content component based on a source of the plurality of content components. ### Claim 5 (depends on 1) The method of claim 1, wherein content mapped to the protected surface is rendered on the display device and prevented from being replicated from the display device. ### Claim 6 (depends on 1) The method of claim 1, further comprising: disabling recording or storing features of the processing platform with respect to the protected surface. ### Claim 7 (depends on 1) The method of claim 1, wherein the protected surface includes a texture having a predetermined dimension that maps to a field of view on the display device. ### Claim 8 (depends on 1) The method of claim 1, further comprising: identifying, by the processing platform, an unencrypted content component among the plurality of content components; and merging, by the processing platform, the encrypted content component and the unencrypted content component into a single output frame; and transmitting, by the processing platform, the single output frame to the display device, wherein the unencrypted content component is mapped to an unprotected surface on the display device. ### Claim 9 (depends on 8) The method of claim 8, further comprising: prior to transmitting the single output frame to the display device, allocating the encrypted content component to the protected surface on the display device and the unencrypted content component to the unprotected surface on the display device. ### Claim 10 (depends on 8) The method of claim 8, wherein the protected surface and the unprotected surface map to mutually exclusive fields of view on the display device. ### Claim 11 (depends on 8) The method of claim 8, wherein the protected surface and the unprotected surface map to two fields of view that overlap on the display device, wherein the overlap between the fields of view is displayed as encrypted content on the display device such that while the encrypted content is rendered on the display device, the encrypted content is prevented from being replicated from the display device. ### Claim 12 A processing platform comprising: one or more processors; and one or more storage devices storing instructions that, when executed on the one or more processors, cause the one or more processors to: receive a plurality of content components; identify an encrypted content component among the plurality of content components; and transmit the encrypted content component to a display device, wherein at least the encrypted content component is mapped to a protected surface. ### Claim 13 (depends on 12) The processing platform of claim 12, wherein the instructions, when executed on the one or more processors, further cause the one or more processors to: identify an unencrypted content component among the plurality of content components; and merge the encrypted content component and the unencrypted content component into a single output frame; and transmit the single output frame to a display device, wherein the single output frame is mapped to one or more protected surfaces on the display device. ### Claim 14 (depends on 12) The processing platform of claim 12, wherein the instructions, when executed on the one or more processors, further cause the one or more processors to: generate the protected surface, wherein the encrypted content component is configured to be rendered only on the protected surface; and transmit the protected surface to the display device, wherein the encrypted content component is rendered on the protected surface on the display device. ### Claim 15 (depends on 12) The processing platform of claim 12, wherein the instructions, when executed on the one or more processors, further cause the one or more processors to: upon receiving the plurality of content components, create a plurality of frame loops, wherein each frame loop corresponds to one of the plurality of content components; queue the plurality of frame loops into a frame loop pipeline; obtain a frame loop from the frame loop pipeline; and determine whether the frame loop corresponds to the encrypted content component or an unencrypted content component based on a source of the plurality of content components. ### Claim 16 (depends on 12) The processing platform of claim 12, wherein content mapped to the protected surface is rendered on the display device and prevented from being replicated from the display device, wherein the instructions, when executed on the one or more processors, further cause the one or more processors to: disable recording or storing features of the processing platform with respect to the protected surface. ### Claim 17 (depends on 12) The processing platform of claim 12, wherein the protected surface includes a texture having a predetermined dimension that maps to a field of view on the display device. ### Claim 18 (depends on 12) The processing platform of claim 12, wherein the instructions, when executed on the one or more processors, further cause the one or more processors to: identify an unencrypted content component among the plurality of content components; and merge the encrypted content component and the unencrypted content component into a single output frame; and transmit the single output frame to the display device, wherein the unencrypted content component is mapped to an unprotected surface on the display device. ### Claim 19 (depends on 18) The processing platform of claim 18, wherein the instructions, when executed on the one or more processors, further cause the one or more processors to: prior to transmitting the single output frame to the display device, allocate the encrypted content component to the protected surface on the display device and the unencrypted content component to the unprotected surface on the display device, wherein the protected surface and the unprotected surface map to mutually exclusive fields of view on the display device. ### Claim 20 (depends on 18) The processing platform of claim 18, wherein the instructions, when executed on the one or more processors, further cause the one or more processors to: prior to transmitting the single output frame to the display device, allocate the encrypted content component to the protected surface on the display device and the unencrypted content component to the unprotected surface on the display device, wherein the protected surface and the unprotected surface map to two fields of view that overlap on the display device, wherein the overlap between the fields of view is displayed as encrypted content on the display device, while the encrypted content is rendered on the display device, the encrypted content is prevented from being replicated from the display device.
