Abstract: The invention provides an oligosaccharide-fluorescent marker, and a preparation method and use thereof. The method includes reacting an oligosaccharide with a fluorescent agent in a solvent in the presence of a reducing agent to obtain the oligosaccharide-fluorescent marker. According to the oligosaccharide-fluorescent marker of the invention, an amino group in the fluorescent agent is subjected to a condensation reaction with a hemiacetal group at a reducing end of the oligosaccharide, to form an imine or Schiff base, and then the imine or Schiff base is reduced into a relatively stable secondary amine by using the reducing agent. In this way, the end of the oligosaccharide is fluorescently marked. The fluorescent group marked at the end has small influence on the biological activity of the oligosaccharide, and the marker has higher fluorescence intensity and is stable under physiological conditions.

Abstract: Sensitive information displayed on a screen is protected against leakage and loss. A section of a bitmap containing sensitive information is defined as a protection region. A protection marker identifying the protection region is embedded into the bitmap. The defined protection region is divided into multiple sub-regions, and a separate sub-region protection marker is embedded in each sub-region of the original protection region. The defining, embedding and dividing are performed before the bitmap is copied to the screen buffer. When content that was displayed on the screen has been captured, for example by screen capturing software, the captured content is parsed. All sub-region protection markers embedded in the captured content are detected, and a real protection region in the captured content is calculated, based on information in the detected sub-region protection markers. The sensitive information in the captured content is erased.
