TESTING FOR CORRECTNESS AND REBASELINING OF IMAGES

An image correctness testing system compares an expected image with an image generated at a device. The system transmits the expected image to the device. The system then analyzes the image that is generated at the device in order to determine a checksum of the image generated at the device. The system further compares the checksum of the image generated at the device with a checksum of the expected image and presents a difference to a user on a web interface. The system can then receive an input from the user to rebaseline the image generated at the device and/or the expected image. On receiving the user input, the system updates the checksum of the expected image equal to the checksum of the image generated at the device or vice versa

Secure public internet access handler (spinach

Abstract: This paper describes a system that controls access to computer networks through publicly accessible LANs, enabling network administrators to authorize users either on a permanent or occasional basis. The system has been designed with minimal assumptions about the software and hardware required of users, and requires very little specialized equipment within the network infrastructure. We enumerate the requirements for such a system, describe the design and implementation of the system, and note tradeoffs between security and efficiency
