A method for transporting valuable documents from a first location to a second location in a break-in protected case provided with means which, on triggering, acts on the valuables in the case, for instance by dye-disfiguration, triggering being controlled by a timing mechanism in the case. The process comprises that the despatcher at the first location, after putting the valuables in the case, locks it and activates the timing mechanism to induce triggering after a given transport time in the lack of any deactivation, that the case is transported from the first location to the second location, and that the recipient at the second location deactivates the timing mechanism in the case and afterwards opens it. The distinguishing features of the method are that an ID sigil is calculated at the first location, based upon a secret recipient key, an algorithm and open data which includes non-fixed data, such as time data, that the calculated sigil is electronically stored in the case in connection with the locking thereof, preferably together with the non-fixed data necessary for sigil calculation, that, in connection with receipt of the case at the second location, and ID sigil is calculated based upon a recipient sigil provided by the recipient, the algorithm and open data, including said non-fixed data, and that a comparison is conducted in the case between the stored sigil and the sigil thus calculated at the second location, correspondence between the sigils permitting deactivation of the time mechanism and allowing opening of the case without any abovementioned acts upon the valuables. |
