A kernel driver(200) operates in a kernel mode, and obtains information, generated in the kernel mode, for the use of digital information from an application of the user mode. By using the obtained information and policy information, the kernel driver controls the right of the use of digital information.

Abstract: A liquid crystal photoaligment agent is provided to ensure excellent liquid crystal orientation, voltage holding rate, pretilt angle, and residual DC as well as good printability, washing stability and anti-fouling property, and to perform liquid crystal uniaxial orientation. A liquid crystal photoaligment agent comprises a polyamic acid copolymer consisting of a repeating unit represented by chemical formula 1 and a repeating unit represented by chemical formula 2; a polyimide copolymer consisting of a repeating unit represented by chemical formula 3 and a repeating unit represented by chemical formula 4; and any one copolymer selected from the group consisting of their combinations. In chemical formulas 1 -4, R1, R3, R5 and R7, are independently a tetravalent organic group induced from acid dianhydride selected from the group consisting of aliphatic ring type tetracarboxylic anhydride and aromatic acid dianhydride.
