Privacy Discussion Clause Samples

Privacy Discussion. Privacy Protection is the ability of individuals in group key management to seclude or reveal their own sensitive information selectively. As discussed in Section 2 that neither tree-based nor contributory group key managements consider privacy protection for individuals. All members share information securely, and individuals cannot manage their own sensitive information in systems. However, HGKM employs the leader constructs a VC with new key which is shared by all VC members and the leader knows group, subgroup, node and cluster keys, so the leader can decipher the information via networks and re-dispatch the information to VC members encrypted with the VC key. The comparison of proposed work (HGKM) to logical key hierarchy (LKH) is summarized in the table 4.1. The entries indicate the number of messages, cryptographic operations and keys required, and the following notations are used: − P,A,L : Passive users, Active users and Leaders, respectively. − n : the number of members in the subgroup. − m : the size of the cluster. − x / y : ‘x’ denotes the cost of the requesting users to join or leave, and ‘y’ denotes the cost of other users. − d : height of the tree, for the balanced tree, d=logαn, n is the number of members. − a : the degree of the tree. − ns : the number of subgroups. − H,D,E : one-way Hash, Decryption and Encryption functions, respectively.

To an active user, it does not involve rekeying operations for joining and leaving. In other words, it does not trigger key updating events through group key server to reduce the load of systems. In addition, the every active user has own VC, it makes the sensitive information of active users more secure; no other active users can access it. Therefore, the scheme is suitable for the sensitive information sharing which needs group communication securely and efficiently.

  • Informal Discussions Before a written grievance is submitted, informal discussions will take place between the aggrieved party, the principal or supervisor and Education Minnesota – OSSEO representative. Through these discussions the parties will attempt to resolve the problem. Subd. 2. Level I: If the grievance is not resolved through informal discussions, the aggrieved party may submit the grievance in writing to the principal or supervisor. A copy of such written grievance must simultaneously be filed with Human Resources. The Director, Human Resources will set a meeting date within five (5) days of receipt of the written grievance. The Director, Human Resources will give a written decision on the grievance to the parties involved within ten (10) days after the meeting. Subd. 3. Level II: In the event the grievance is not resolved in Level I, the decision rendered may be appealed to the superintendent of schools, provided such appeal is made in writing within five (5) days after receipt of the decision in Level I. If a grievance is properly appealed to the superintendent, the superintendent or designee will set a time to meet regarding the grievance within fifteen (15) days after receipt of the appeal. Within ten (10) days after the meeting, the superintendent or designee will issue a decision in writing to the parties involved. Subd. 4.
