Provided is an anti-counterfeiting composition for anti-counterfeiting fibers, including a carrier, an anti-counterfeiting tracer and a dispersant, wherein the anti-counterfeiting tracer is composed of barium oxide, strontium oxide, aluminum oxide and zinc oxide, and a barium element content, a strontium element content, an aluminum element content, and a zinc element content in the anti-counterfeiting composition is controlled to a fixed feeding mass ratio; in percent by mass, the sum of the barium element content, strontium element content, aluminum element content, and zinc content accounts for 5-50% of the anti-counterfeiting composition; the carrier is a matrix polymer or a bio-derived oil. The anti-counterfeiting composition of the present disclosure can give the anti-counterfeiting fiber advantages of memory tracking properties and identification functions, high anti-counterfeiting capability, and good anti-counterfeiting concealment.
