Electronic data is the most frequently used evidence in the internet and information era. Electronic data has been applied extensively and can be classified into many categories, which determine that electronic data contains all kinds of fundamental rights. To clearly understand the fundamental rights contained in electronic data is an important precondition for respecting and protecting human rights in electronic data evidence obtainment. Property-type electronic data contain property rights. Traditional investigation measures such as seizure and freezing the property cannot be taken to obtain valid evidence. To directly turn the digital currency into cash and then seize the cash, will result in insufficient property rights protection, and may violate other fundamental rights of criminal suspects. The expansion of the object of the right to privacy and the change of the carrier on which the expansion depends in privacy-type electronic data, determine that the obtainment of the privacy-type electronic data evidence may result in intangible intervention and secondary intervention in the right to privacy. Communication-type electronic data contains freedom of communication and the right to communication secrecy. Investigative organs can collect this kind of electronic data through search, acquisition, remote investigation and examination, and other means. However, according to the existing institution design, the above-mentioned means may result in insufficient protection of freedom of communication. Expression-type electronic data contains freedom of expression. If investigative organs collect this kind of data, they may intervene in freedom of the press though they do not intervene in narrowly defined freedom of expression. The basic principles that should be followed in the electronic data evidence obtainment which intervenes in fundamental rights include the doctrine of legal reservation, the writ system, the principle of proportionality, and illegal evidence exclusion.
