Meaningful image encryption algorithm based on compressive sensing and integer wavelet transform

A new meaningful image encryption algorithm based on compressive sensing(CS)and integer wavelet transformation(IWT)is proposed in this study.First of all,the initial values of chaotic system are encrypted by RSA algorithm,and then they are open as public keys.To make the chaotic sequence more random,a mathematical model is constructed to improve the random performance.Then,the plain image is compressed and encrypted to obtain the secret image.Secondly,the secret image is inserted with numbers zero to extend its size same to the plain image.After applying IWT to the carrier image and discrete wavelet transformation(DWT)to the inserted image,the secret image is embedded into the carrier image.Finally,a meaningful carrier image embedded with secret plain image can be obtained by inverse IWT.Here,the measurement matrix is built by both chaotic system and Hadamard matrix,which not only retains the characteristics of Hadamard matrix,but also has the property of control and synchronization of chaotic system.Especially,information entropy of the plain image is employed to produce the initial conditions of chaotic system.As a result,the proposed algorithm can resist known-plaintext attack(KPA)and chosen-plaintext attack(CPA).By the help of asymmetric cipher algorithm RSA,no extra transmission is needed in the communication.Experimental simulations show that the normalized correlation(NC)values between the host image and the cipher image are high.That is to say,the proposed encryption algorithm is imperceptible and has good hiding effect.

Traditional image encryption algorithms transform a plain image into a noise-like image.To lower the chances for the encrypted image being detected by the attacker during the image transmission,a visually meaningful image encryption scheme is suggested to hide the encrypted image using another carrier image.This paper proposes a visually meaningful encrypted image algorithm that hides a secret image and a digital signature which provides authenticity and confidentiality.The recovered digital signature is used for the purpose of identity authentication while the secret image is encrypted to protect its confidentiality.Least Significant Bit(LSB)method to embed signature on the encrypted image and Lifting Wavelet Transform(LWT)to generate a visually meaningful encrypted image are designed.The proposed algorithm has a keyspace of 139.5-bit,a Normalized Correlation(NC)value of 0.9998 which is closer to 1 and a Peak Signal to Noise Ratio(PSNR)with a value greater than 50 dB.Different analyses are also performed on the proposed algorithm using different images.The experimental results show that the proposed scheme is with high key sensitivity and strong robustness against pepper and salt attack and cropping attack.Moreover,the histogram analysis shows that the original carrier image and the final visual image are very similar.

Images,as a multimedia resource,for example,medical,education,sensing,and military images,have been playing an important role in digital information communications.To prevent unauthorized access and protect the security of an image,a direct approach is to encrypt the image[1,2]to hide its information.Chaotic maps(systems)have some excellent inherent properties[3,4],such as nonlinearity,sensitivity to initial conditions,and ergodicity.Therefore,they have received increasing attention and have been widely used in

港口“多品种,小批量”的原料取配送服务助力钢厂实现JIT生产,但取料机故障等作业突发事件也成为制约“港-钢”连续作业与生产的重要因素。因此,本文基于柔性生产机制提出精细化取料工艺,并以作业完成时间最小化为目标建立取料机应急调度模型,设计IBFA算法进行求解。最后,结合故障事件进行仿真实验,得出并分析了取料机应急调度方案。结果表明,应急调度可有效降低突发事件带来的影响,提高港口作业的柔性和效率,为实现港口物流链与钢厂生产链的无缝衔接提供科学的理论与方法。

推动“体文旅”产业融合发展既是大众消费结构升级的现实需要,也是满足人民群众对美好生活向往的必然要求。运用熵值法、耦合协调度模型、核密度估计法和莫兰指数对2015—2021年我国东部、中部和西部三大经济区域11个省(自治区、直辖市)的“体文旅”产业综合发展态势、融合发展测度及时空演化特征进行分析,结果表明:考察期内“体文旅”产业综合发展水平整体不断提升,呈上升态势;时空演化方面,产业融合协调水平整体发展势头良好,但产业融合协调等级整体偏低;空间关联方面,产业融合协调水平在空间上显著正相关,存在空间集聚的特征。基于此,提出建议:区域创新协同,构建融合发展新体系;产业结构协同,促进融合发展新平衡;时空演化协同,打造融合发展新局面;空间关联协同,共建融合发展良性生态圈。

杜甫在诗中大量书写了个人“寒”“热”之体验。杜诗的寒热书写本于古典诗歌吟咏情性之本质,并受汉魏六朝诗人创作以及杜甫多年坎坷人生所影响。杜诗中的“寒”“热”不仅是对个人体感的描述,也包含了对外物的书写以及自我内心之困的形象表达。寒热书写是杜诗抒情之角度,体现杜甫对困顿人生的感叹、对苍生的关切以及自身精神困境的自述。“寒”“热”作为杜甫感物书写之艺术形式,影响了中唐诗人韩愈诗歌体物之书写,对“禁体物”诗歌创作开辟思路;同时白居易等讽喻诗人也学习杜甫以“寒”“热”书写民生。

International Journal of Agricultural and Biological Engineering 2021年第1期14卷 230-236页

This study assessed the combined effect of slightly acidic electrolyzed water(SAEW)and slightly acidic electrolyzed water ice(SAEW-ice)on the quality of pomfrets over a period of 18 d of cold storage at 4°C.A presoak for 5 min in SAEW solution(22 mg/L)was used before the pomfrets were placed on SAEW-ice(pH:6.45;ORP:803 mV;ACC:18 mg/L);The changes in physicochemical properties(i.e.,pH,thiobarbituric acid,total volatile basic nitrogen and texture profile),microbial loads and sensory characteristics were all analyzed.Compared with the tap water(TW)group,the total bacterial counts of the SAEW group significantly decreased by 1.27 log10 CFU/g after immersion(p<0.05).The shelf life of the pomfrets was prolonged by 9 d by the combined treatment of SAEW and SAEW-ice during storage at 4℃.On the 18th day,the gumminess and chewiness values of the pomfrets in the SAEW+SAEW-ice group were 195 g and 3.97 mJ,respectively,which were significantly higher than those of the other groups(p<0.05).The results suggested that SAEW+SAEW-ice treatments have great potential as a novel method to maintain the quality and extend the shelf life of pomfrets during refrigerated storage.
