Internet protocol (ip) whitelisting for signed uniform resource locators (urls)

A method comprising:

• receiving, from a first user device, a first request to access a resource;
• determining, based on the first request, a first identifier of the first user device in response to receiving the first request from the first user device;
• upon authenticating the first user device, generating a pre-signed Uniform Resource Locator (URL) indicating a location of the resource, wherein the pre-signed URL comprises an indication that the first user device is permitted to access the resource;
• generating a signed URL by prefixing the pre-signed URL with the first identifier of the first user device, wherein the signed URL is encrypted with a signing key associated with the first user device;
• receiving a second request to access the resource, wherein the second request comprises the signed URL;
• determining a second identifier corresponding to the second request;
• and
• based on comparing the second identifier with the first identifier in the signed URL, granting or denying the second request access to the resource.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a computing device to:

• receive, from a first user device, a first request to access a resource;
• determine, based on the first request, a first identifier of the first user device in response to receiving the first request from the first user device;
• upon authenticating the first user device, generate a pre-signed Uniform Resource Locator (URL) indicating a location of the resource, wherein the pre-signed URL comprises an indication that the first user device is permitted to access the resource;
• generate a signed URL by prefixing the pre-signed URL with the first identifier of the first user device, wherein the signed URL is encrypted with a signing key associated with the first user device;
• receive a second request to access the resource, wherein the second request comprises the signed URL;
• determine a second identifier corresponding to the second request;
• and
• based on comparing the second identifier with the first identifier in the signed URL, grant or deny the second request access to the resource.
