a screen capture software application comprising a plurality of programming instructions configured to be uploaded to a client device via a network for operation on a processor thereof; a web server comprising a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, and configured to receive interaction from the client device via the network; wherein the web server is further configured to upload the screen capture software application to the client device; and wherein the screen capture server is directed by the web server to receive screen capture data from the uploaded screen capture software application. ### Claim 2 (depends on 1) The system of claim 1, wherein the screen capture data comprises image data based at least in part on an image being shown on a connected display hardware device operating on the client device. ### Claim 3 (depends on 1) The system of claim 1, wherein the screen capture data is stored for future reference. ### Claim 4 (depends on 1) The system of claim 1, wherein the screen capture data is presented to a human user for review via a display hardware device operating on a computing device configured to communicate with the screen capture server. ### Claim 5 (depends on 1) The system of claim 1, wherein the screen capture software application is further configured to compress the screen capture data prior to transmission, and the screen capture server is further configured to decompress the screen capture data upon receipt. ### Claim 6 (depends on 1) The system of claim 1, wherein the screen capture data further comprises location data based at least in part on the physical location of the client device. ### Claim 7 (depends on 6) The system of claim 6, wherein the location data is based at least in part on a network address of the client device. ### Claim 8 (depends on 1) The system of claim 1, wherein a portion of the screen capture data is modified by the screen capture software application prior to transmission. ### Claim 9 (depends on 8) The system of claim 8, wherein the modification comprises the obfuscation of data. ### Claim 10 (depends on 8) The system of claim 8, wherein the modification comprises the removal of data. ### Claim 11 A method for zero-footprint screen capture, the method comprising the steps of: receiving, at a web server comprising a processor, a memory, and a plurality of software programming instructions stored in the memory and operating on the processor, an interaction from a client device via a network; uploading to the client device a screen capture software application comprising a plurality of programming instructions configured to cause a processor to capture screen capture data from the client device and to transmit the screen capture data to a screen capture server comprising a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor; and receiving and storing screen capture data from the screen capture software application at the screen capture server.
