Outsourcing spatial database to a third party is becoming a common practice for more and more individuals and companies to save the cost of managing and maintaining database, where a data owner delegates its spatial data management tasks to a third party and grants it to provide query services. However, the third party is not full trusted. Thus, authentication information should be provided to the client for query authentication. In this paper, we introduce an efficient space authenticated data structure, called Verifiable Similarity Indexing tree (VSS-tree), to support authenticated spatial query. We build VSS-tree based on SS-tree which employs bounding sphere rather than bounding rectangle for region shape and extend it with authentication information. Based on VSS-tree, the third party finds query results and builds their corresponding verification object. The client performs query authentication using the verification object and the public key published. Finally, we evaluate the performance and validity of our algorithms, the experiment results show that VSS-tree can efficiently support spatial query and have better performance than Merkle R tree (MR-tree)

The Cost

Although punishment can promote cooperative behavior, the evolution of punishment requires benefits which override the cost. One possible source of the benefit of punishing uncooperative behavior is obtaining a positive evaluation. This study compares evaluations of punishers and non-punishers. Two hundred and thirty-four undergraduate students participated in two studies. Study 1 revealed that, in the public goods game, punishers were not positively evaluated, while punishers were positively evaluated in the third-party punishment game. In Study 2, where the non-cooperator was a participant of a public goods game, we manipulated the punishers participation in the game. The results showed that punishers received no positive evaluations, regardless of their participation in the game, indicating that negative evaluation may not be a reaction toward aggression with retaliatory intentions.

Alternative dispute resolution (ADR), particularly mediation, plays a key role in reducing the costs of civil disputes by fomenting the early settlement of cases. This chapter discusses ADR processes; advantages or disadvantages of ADR and litigation; the cost of ADR; reference to ADR; and court involvement in ADR. Adjudicative ADR results in the third party neutral deciding the dispute or difference between the parties. Non-adjudicative ADR processes involve moving the parties towards reaching a compromise agreement between themselves. Rules of court require parties to consider using ADR.

In Cloud Storage Server, data integrity plays an important role, given cloud clients might not be aware whether the data is safe or has been tampered with. This system introduces identity-based signature algorithms to protect data that belongs to the data owner and gets the status of cloud data by means of verification through signatures. Since it is practically not possible for the data owner to be available online all the time for checking cloud data integrity, Third party auditor is tasked with verifying the data integrity every time instead of data owner. The Third party auditors should not read the cipher text data while verifying and must authenticate itself to cloud server by performing Proof of Knowledge operation; then cloud server can reveal the sensitive data as block wise and the third party auditor can verify the signature without knowledge of cipher text data. Finally, an audit report is sent to the data owner. This work demonstrates data security and integrity in the cloud..
