Methods and systems for user authentication and file access control

A file management system, comprising:

• a server, wherein the server is configured to:
• store a file in non-volatile memory;
• receive from a first client device a request to generate a uniform resource identifier (URI), wherein the first URI is associated with the file, an identity, and a dynamic expire time;
• generate a uniform resource identifier (URI) associated with the file, wherein the URI links to a resource comprising the file;
• transmit at the request of the first client device the URI to a second client device;
• receive, from a second client device, a request using the URI to request the resource;
• validate the identity as an authorized identity, wherein the server checks the identity as being contained in a database of authorized identities on the server;
• validate the identity through an identity provider, wherein the identity provider requests a login to the identity on an identity hosting platform;
• and
• grant or deny access to the resource based on a response from the server and the identity provider.

A non-transitory computer readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to control access to generated files by:

• storing by a server a file in non-volatile memory;
• receiving by the server from a first client device a request to generate a uniform resource identifier (URI), wherein the first URI is associated with the file, an identity, and a dynamic expire time;
• generating at the server a uniform resource identifier (URI) associated with the file, wherein the URI links to a resource comprising the file and is generated at the server;
• transmitting by the server at the request of the first client device the URI to a second client device;
• receiving at the server from a second client device a request using the URI to request the resource;
• validating the identity through the server as an authorized identity, wherein the server checks the identity as being contained in a database of authorized identities in the server;
• validating the identity through an identity provider, wherein the identity provider requests a login to the identity on an identity hosting platform;
• and
• granting or denying access to the resource based on a response from the server and the identity provider.
