Protecting content-stream portions from modification or removal

A computer-implemented method comprising:

• obtaining a request from a client computing device to receive streaming content, wherein the streaming content is represented by a plurality of content portions that are identified by a first set of identifiers;
• generating a concealed manifest for the streaming content, wherein the concealed manifest includes a set of concealed identifiers that utilize a single identification scheme common among the set of concealed identifiers to identify the plurality of content portions, wherein each concealed identifier corresponds to an identifier within the first set of identifiers, and wherein the concealed identifiers within the concealed manifest, in their concealed form and without modification of the concealed identifiers into an unconcealed form, indicate an order of output of the plurality of content portions to form the streaming content;
• and
• transmitting the concealed manifest to the client computing device, wherein the client computing device is configured to transmit one or more requests for individual content portions of the plurality of portions, the one or more requests identifying the individual content portions in the requests using the concealed identifiers for the individual content portions.

One or more non-transitory computer-readable media comprising computer-executable instructions that, when executed by a computing system, cause the computing system to:

• obtain a request from a client computing device to receive streaming content, wherein the streaming content is represented by a plurality of content portions that are identified by a first set of identifiers;
• generate a concealed manifest for the streaming content, wherein the concealed manifest includes a set of concealed identifiers that utilize a single identification scheme common among the set of concealed identifiers to identify the plurality of content portions, wherein each concealed identifier corresponds to an identifier within the first set of identifiers, and wherein the concealed identifiers within the concealed manifest, in their concealed form and without modification of the concealed identifiers into an unconcealed form, indicate an order of output of the plurality of content portions to form the streaming content;
• and
• transmit the concealed manifest to the client computing device, wherein the client computing device is configured to transmit one or more requests for individual content portions of the plurality of portions, the one or more requests identifying the individual content portions in the requests using the concealed identifiers for the individual content portions.
