Method to isolate image capturing devices between remote desktop sessions for scanner redirection

A non-transitory computer-readable medium comprising instructions that are executable in a remote desktop computer system, wherein the instructions when executed cause the remote desktop computer system to carry out a scanner redirection method, the remote desktop computer system including a plurality of client computers and a remote computer, and the remote computer concurrently having a first remote desktop session with a first client computer of the client computers and a second remote desktop session with a second client computer of the client computers, and wherein the scanner redirection method comprises:

• determining, by the remote computer by communicating with the first client computer, that the first client computer has installed first drivers of one or more first image capturing devices, and based on the first client computer having installed the first drivers, creating a first list of the one or more first image capturing devices, the first list being accessible to the first remote desktop session but being inaccessible to the second remote desktop session;
• determining, by the remote computer by communicating with the second client computer, that the second client computer has installed second drivers of one or more second image capturing devices, and based on the second client computer having installed the second drivers, creating a second list of the one or more second image capturing devices, the second list being accessible to the second remote desktop session but being inaccessible to the first remote desktop session;
• transmitting, by the remote computer to the first client computer after receiving a selection of a first image capturing device from the first list, an identifier (ID) of the selected first image capturing device and a request to acquire a first image;
• and
• receiving the requested first image by the remote computer from the first client computer, and then providing the received first image by the remote computer to an application running on the remote computer in the first remote desktop session, the first image being created by the selected first image capturing device.

A remote computer of a remote desktop computer system, the remote desktop computer system comprising a plurality of client computers including a first client computer and a second client computer, and the remote computer concurrently having a first remote desktop session with the first client computer and a second remote desktop session with the second client computer, wherein the remote computer is configured to execute on a processor of a hardware platform to:

• determine, by communicating with the first client computer, that the first client computer has installed first drivers of one or more first image capturing devices, and based on the first client computer having installed the first drivers, create a first list of the one or more first image capturing devices, the first list being accessible to the first remote desktop session but being inaccessible to the second remote desktop session;
• determine, by communicating with the second client computer, that the second client computer has installed second drivers of one or more second image capturing devices, and based on the second client computer having installed the second drivers, create a second list of the one or more second image capturing devices, the second list being accessible to the second remote desktop session but being inaccessible to the first remote desktop session;
• transmit, to the first client computer after receiving a selection of a first image capturing device from the first list, an identifier (ID) of the selected first image capturing device and a request to acquire a first image;
• and
• receive the requested first image from the first client computer, and then provide the received first image to an application running on the remote computer in the first remote desktop session, the first image being created by the selected first image capturing device.
