Abstract
The article compares the regulations concerning postal secrecy and telecommunications secrecy with respect to the following structural elements of both: objective scope, subjective scope, protection period, scope of freedom of the obligated entity, rules of access for entitled services, rules for controlling maintenance of secrecy and sanctions for disclosure of confidential information. The comparison has revealed that the regulation of telecommunications secrecy is much more extensive. Many differences are dues to the specificity of the regulated communication medium, and that difference is also the main reason why telecommunications secrecy has been regulated in greater detail.
