. . . . for human interactions and especially a platform for legal interactions, including legal actions and events. In the interactions of the real and physical world, people try to prove their Claims in cases of disputes and legal actions by preparing paper documents in transactions and legal relations with each other. The physical nature of these documents has made it easier to create and protect them. In the Cyber space, people must prepare documents and maintain these documents to prove their rights. Considering the fact that Iran's evidence system is a legal evidence system, the evidence presented by the parties must have legal conditions, at the same time, these documents and evidence are subject to change every day due to the dynamics and evolution of the Cyberspace, the challenges The acceptance of these evidences in the legal system of our country is a matter of debate. This article is written in a descriptive and analytical way and according to the provisions of the commercial law and the definition of the document in the civil law, in terms of the legal divisions of the evidence in this space, it can be classified as deed under private seal, secure electronic documents and documents in the form of a official document. there are also challenges such as the expensiveness of searching for these evidences, attribution of documents, determination of the governing law among these challenges.

The subject of this article is the existential belonging of humans in the Cyber space. The relationship between man and old technology was instrumental; That is, technology was a human tool and he did not have an existence based on technology. But human consistency is new to modern technology. Or in other words, the new humanity has an existential poverty or an existential belonging in relation to technology. None of his spheres of existence are independent from technology, but rather are completely dependent on it. In other words, in the old technology, human beings were independent from it and lived without it. This technology was not more than a tool. But the existential consistency of the new human being is due to technology; Without it, his personal and social life will fall apart. By using the discussion of causation in Islamic philosophy, we can gain a special understanding of the relationship between humans and new technology and Cyber space. It seems that this discussion can give a special model in this field, which will make understanding this relationship easier from a philosophical point of view.

in the Cyber space tow group players are acting. one of them are internet intermediates such as internet service provider and site mangers and data producer also second group of them are users that are end consumers of internet service. the resource of making tort in the Cyber space is same with others resource in the actual world because of nature difference between Cyber space and actual world we cannot performance total rules of basic tort in Cyber space all so we cannot performance same and one doctrine about this world. in this paper we try to reconnaissance the players who are present in the Cyber space. and we could comparison resource of making tort in actual world white Cyber space. at end we try to comparison important doctrine about base of tort in Cyber space. finally we cannot performance all rules of tort that there is in actual world in the Cyber space but we should be more inventor

The present study aims to investigate the possibility of creation of trust culture in Cyber space regarding its structural properties. We used the theory of social trust by Piotr Sztompka and Handerson as the theoretical framework of the study. The study was conducted in the city of Islamshahr in December 2012. The statistical population included all the people who went to an internet café in the cityfrom whom 383 people were chosen as the sample. The results indicate that trust culture has been formed in the Cyber space, however at a lower average level compared to the physical world. The results also show a direct relation between the structure of Cyber space and the formed trust culture. The structure of Cyber space showed a stronger relation with the mental dimension of trust culture rather than its objective dimension. Different Cyber space environments showed different levels of trust culture. Facebook showed the strongest trust culture and emails and game environments came in second and third level.
