Tamper indicating seal

A method for detecting tampering with a seal, the method comprising:

• passing a seal wire through a seal housing, the seal housing comprising a piston and defining a plunger chamber;
• inserting a plunger body into the plunger chamber, the plunger body defining an adhesive cavity filled with an adhesive that is contained within the adhesive cavity by a penetrable seal, the piston being configured for puncturing the penetrable seal, engaging the adhesive cavity, and expressing the adhesive from the adhesive cavity into a space between the plunger body and the seal housing;
• curing the adhesive to generate a unique identifier;
• obtaining a reference image of the seal housing and the unique identifier;
• obtaining a validation image of the seal housing and the unique identifier;
• comparing the reference image to the validation image to determine if the unique identifier has changed.

A tamper indication system comprising:

• a loop seal tamper indicating device comprising:
• a seal wire;
• a seal housing for receiving the seal wire, the seal housing comprising a piston and defining a plunger chamber;
• and
• a plunger body configured for inserting into the plunger chamber, the plunger body defining an adhesive cavity containing an adhesive and comprising a penetrable seal for containing the adhesive within the adhesive cavity, the piston being configured for puncturing the penetrable seal and engaging the adhesive cavity to express the adhesive from the adhesive cavity into the plunger chamber when the plunger body is inserted into the seal housing;
• and
• a seal reader assembly comprising:
• a lighting assembly that illuminates the seal housing at one or more angles;
• and
• a camera assembly that takes images of the illuminated seal housing.
