摘　　要：【目的】通过数据卸载,智能用户设备将自身不能及时处理的数据借助云端服务器进行处理,减轻用户设备自身的处理压力,提高数据处理质量。但当传输的数据涉及用户隐私数据时,对其提供保护就显得尤为重要。【方法】将异或编码和隐写技术相结合,提出基于异或编码隐写的安全数据卸载方法。当用户设备产生敏感隐私数据后,先对该部分数据进行异或编码加密,再通过隐写技术隐写在数字图像载体中,将含有隐写信息的载体通过网络传输到云端,进而对其中的敏感隐私数据进行处理。【结果】通过实验,成功模拟了基于异或编码进行隐写的过程,并对隐写后的图像载体进行视觉攻击分析。【结论】该方法可以从数据加密和数据隐藏两方面对敏感隐私数据进行保护,对数据安全卸载具有重要意义。[Purposes]Through data offloading,intelligent user devices can process data that cannot be processed in time by themselves with the help of cloud servers,thereby reducing the processing pressure of user devices and improving the quality of data processing.However,when the data transmitted in⁃volves the user′s private data,how to protect it is particularly important.[Methods]In this paper,a se⁃cure data offloading method based on XOR coding steganography is proposed by combining XOR coding with steganography.When the sensitive privacy data is generated by the user device,the part of the data is first XOR encoded and encrypted,and then the digital image containing steganographic information is steganized in the digital image through the network to the cloud for processing.[Findings]The process of steganography based on XOR coding is simulated by experiments,and the visual attack of stegano⁃graphic image carrier is analyzed.[Conclusions]This method can protect sensitive privacy data from two aspects:data encryption and data hiding,which is of great significance for the safe offloading of data.
