This paper attempts to study the sustainable adoption of e-government services in northern Iraq. The well-known unified theory of acceptance and use of technology (UTAUT) is applied and extended to study citizens’ behavior regarding e-government services. A quantitative technique was utilized to gauge the efficiency of the model. Overall, 371 replies were received through distributing samples. SPSS software was used for the data evaluation. Two extra constructs were introduced in the study, i.e., “Trust of system (TOS)” and “Ethics of Internet (EOI)”, into the original UTAUT as the theoretical extension. The findings indicate that all constructs have a significant influence on the intention to use e-government services. Moreover, the EOI moderates the effects of TOS on social impacts (SI), performance expectancy (PE), and behavior intention (BI). The results also indicated that there were statistically significant differences in the demographic characteristics of age, educational level excluding gender, and behavioral intention to use e-government services. The study’s results support most of the hypotheses. The results contribute to a better knowledge of the factors affecting the sustainable adoption of e-government in northern Iraq.

Digital RGB color images are considered as the most widely used data type through the internet, so there is a need for efficient and secure techniques to transmit and protect these digital images and this is a matter of high priority process. Many researchers had developed different techniques to increase the security of image transmission, and most of these techniques suffer from the low speed of the encryption-decryption process. In this paper, a novel technique is proposed that could be used for digital color image encryption-decryption. The performance of this technique is compared with the performance of other techniques and it has shown the advantages of using this technique over other techniques in enhancing the throughput and speed of encryption-decryption process.
