The increase in cyber crimes such as theft and piracy adds to the vulnerability of storing and sending image data in cyberspace.To deal with the rampant crime in cyberspace, especially in image data, cryptography is implemented on images.Cryptography based on chaos theory was chosen because it has a random key generator value.Implementation of image cryptography based on chaos theory makes image cryptography more developed, chaos-based algorithms that have been implemented are the Algorithm Arnold Cat Map, Baker's Map, Ikeda Map, Tent Map, Logistic Map 3, Gauss Iterated Map, Henon Map, and Duffing Map Gingerbreadman Map.Of the many algorithms implemented previously in 2016 against the Logistic Map 3, Gauss Iterated Map, Henon Map, Duffing Map Gingerbreadman Map algorithms, comparisons and analysis of encryption time, decryption time, key sensitivity, histogram, lossy and lossless in the decrypted image have been carried out.In this study, the Tinkerbell Map algorithm was initiated to be implemented in image cryptography and compared to the Logistic Map 3 algorithm, Gauss Iterated Map, Henon Map, Duffing Map Gingerbreadman Map.Also added correlation coefficient analysis, MSE and PSNR analysis, to analyze the security of encrypted images.Based on testing of Logistic Map 3, Gauss Iterated Map, Henon Map, Duffing Map Gingerbreadman Map, Tinkerbell Map have different performance.The histogram analysis produces a very good spread of pixels, each algorithm has a different key sensitivity, the highest is the Tinkerbell Map.Henon Map is the best algorithm for correlation coefficient, MSE and PSNR.Time analysis found that the Tinkerbell Map algorithm has the longest process value, and the fastest is logistics map 3. General TermsThe increase in cyber crimes such as theft and piracy adds to the vulnerability of storing and sending data in cyberspace.Unknowingly, data and information that should be used for personal consumption are vulnerable to being exploited by irresponsible parties.In addition, there are many applications that can be used to manipulate data and information, especially data in the form of images.This is a concern for users about data and information security.The more complicated the method used, the better the resulting level of security.
