ISO 18185-4:2007
Scope
This part of ISO 18185 specifies requirements for the data protection, device authentication and conformance
capabilities of electronic seals for communication to and from a seal and its associated reader. These
capabilities include the accessibility, confidentiality, data integrity, authentication and non-repudiation of stored
data.
The protection of this information is provided through a radio-communications interface providing seal
identification and a method to determine whether a freight container’s seal has been opened.
This part of ISO 18185 specifies a freight container seal identification system, with an associated system for
verifying the accuracy of use, having:
⎯ a seal status identification system;
⎯ a battery status indicator;
⎯ a unique Seal Identifier including the identification of the manufacturer;
⎯ a seal (tag) type.
This part of ISO 18185 is intended for use in conjunction with the other parts of ISO 18185.
This part of ISO 18185 is designed to facilitate electronic device authentication. For mechanical seals, the seal
manufacturer is able to determine the authenticity of the device if and when necessary, e.g. to determine the
unauthorized opening of the seal. There are electronic authentication methods which can provide similar
validation without visual inspection. This part of ISO 18185 provides only the guidelines for those methods.
This part of ISO 18185 applies to all electronic seals used on freight containers covered by International
Standards ISO 668, ISO 1496-1 to ISO 1496-5 and ISO 8323 and should, wherever appropriate and
practicable, also be applied to freight containers other than those covered by these International Standards.
