1. A method for information transmission, wherein electronic information is transmitted from a transmission terminal of a transmitter(S) to a receiver terminal of a receiver (E), the method comprising the following steps:
a first transaction step (c), in which a first data record comprising at least one hash value is generated by the transmission terminal and the first data record is transferred to a blockchain,
a first verification step (d), in which the first data record is verified in the blockchain, and stored as a first verified data record,
a second transaction step (I), in which a second data record comprising at least a public receiver key or a receiver identifier is generated by the receiver terminal and the second data record is transferred to the blockchain,
a second verification step (m), in which the second data record is verified in the blockchain and stored as a second verified data record,
a third transaction step (p), in which a third data record is generated by the transmission terminal and transferred to the blockchain,
a third verification step (q), in which the third data record is verified in the blockchain and stored as a third verified data record,
a data encryption step (o, t, u), in which data encrypted by means of the public receiver key are generated by the transmission terminal,
a transmission step, in which the encrypted data are transmitted to the receiver terminal, and
a data description step (v, w, y), in which the electronic information is made accessible to the receiver (E) by the encrypted data being decrypted by the receiver terminal by means of private receiver key;
wherein an information identifier is assigned to the electronic information,
wherein the information identifier is generated by the transmission terminal and transferred to the blockchain as part of the first data record in the first transaction step (c), or
wherein the information identifier is generated by the blockchain and transferred to the transmission terminal in a transfer step (e),
wherein at least the second data record and the third data record comprise the information identifier; and
wherein an announcement step (f) is carried out, in which an announcement data record is stored in a database to which the receiver (E) has access via the receiver terminal, the announcement data record comprising at least a description, intended for publication, of the electronic information and the information identifier.
