The article proposes a personal approach to the formation in Russian legislation a closed system oflimiting access to information that is a system with several types of secrets. Under the presented conception,the secrets are classified by the type of their formation. Primary secrets directly related to theactivity of a subject and ensure his right to the restricted access to the information. Such secrets dealwith the information processed by the subject during his activity. Derived secrets relate to the obligationof a subject as to the protection of information of another subject and communicated on a secret basis(regime of confidentiality). The article specifies the elements of legal regime for each type of secretsincluding subjective elements and the elements of legal regulators. The article proposes the principlesof transforming the regimes for secrets when transmitting information. It studies the regimes of confidentialityacceptable to protect personal data (commercial secret, professional secret, state secret,business secret) and makes a conclusion on the necessity to use these regimes instead of establishingan independent regime of the personal data protection. The author examines certain problems of protectingpersonal data in the regime of commercial secret, related to the RF Labour Code and the Federallaws On Commercial Secret and On Personal Data. The paper also formulates the conditions of achievingthe balance of interests of the subject of personal data (employee) and the operator (employer).A question is studied as to the balance of responsibility of norms for disclosing different types of secrets.It is noted that the balance of sanctions is inconsistent. In particular, maximum sanctions for disclosingcommercial or state secrets are equal, the balance has not been arranged properly as to the criminal liabilityfor breaching privacy (breaching the secret of correspondence, disclosing the secret of adoption),sanctions vary too much in relation to the disclosure of professional secrets. All these aspects requirethe further development of liability measures within the system of secrets.
