Wildlife plays an important role in balancing the earth’s ecosystem. Today, many species of wildlife are threatened with extinction. Images are important input data for wildlife surveillance technology,whichallowsreal situations in the field to be observed and analysed. This project proposed a wireless transmission systemof compressedandsecured imagesusing the SoCFPGA platformfor improving the existing systemin terms of image data collection. Image compression ensuredthat the proposed system wasefficient in terms of data processing, transmission and storage. Image data encryption aimed at ensuring that the security of the transmitted image data would not be hijacked by poachers or non-authorities and ultimately this system wouldtransmit compressed and secured images wirelessly to provide real-time data. The prototype usedLabVIEW 2017 software and NI myRIO (as image transmitter) and a computer (as image receiver) hardware. This platform has been utilisedfor the development of the architectural design of a compression system using the discrete cosine transform (DCT) method, the development of an encryption system using the advanced encryption standards (AES) method and wireless transmission using Wi-Fi. The implementation of DCT on the field-programmable gate array (FPGA) platform allowedthe imagesto be compressed by an average of 44% to shortenthe time used in the transmission process. The AES method guaranteeddata security with images that can only be viewedwhenusing the correct password. Combining both the DCT and AES methods, the rapid prototyping of the wireless transmission of compressed and secured images for a wildlife surveillance system equippedwith a motion sensor and a camera was developed to detect motion, capture imagesand transmit three (3) different image resolutions atdistances of up to 60m.
