    Purpose of Seals their work

    Security seals are a tool to deter and detect unauthorized opening of a closure. They differ from locks in that they are intended to be used only once, and then destroyed. Early seals were intentionally made to be readily cut open after use. In last 30 – 35 years the added dimension of providing a one-time physical barrier to opening has become popular. Thus, some seals function both as a strong disposable lock and a lock and a seal - to provide evidence of entry or violation.

    When seals are found violated or tampered it is that indicator which tells the user to begin investigating, ultimately catching and stopping the violator. Seal violation most often involves opening and false closing, meant to appear closed and fool the observer. Other violations include substitution of parts, modification of marking, or substitution of whole (clone / duplicate) seals. The initial discovery of tempering or substitution may take place while the seal is in place, when the seal is taken out of use, or it can also be discovered in a post – marten examination of the seal at another location. If not examined by informed persons, tempering or violation of the seal may not be discovered at all.

    Once violation is discovered, the process is to systematically narrow the time and / or place the violation occurs. This is done by a variety of common techniques including more frequent inspection, surveillance, assitional hidden indicators, or questing of those nearby or involved. These actions will eventually tell an investigator who is violating (or attempting to violate) a sealed closure, where and / or when.

    High value goods and items more accessible to unknown persons are the most likely to be protected by strong seals.
