Baroqueing was a Culture technique for securing inactive constructs.[1]
The entire volume of a baroqued object was fractally inscribed with partially random, non-predictable designs[1]; this went down to the atomic level[2] and consumed less than 1% of the object's mass. Nano-devices were hidden within the inscription; the devices damaged or destroyed the object if the object was reactivated by unauthenticated entities. Some of these devices could only be reliably detected by scanning the individual atoms of the object.[1]
Baroqueing manifested on the surface of an object as a full-body tattoo of extreme complexity.[2][1]
