Recently,there has been a sudden shift from using traditional office applications to the collaborative cloud-based office suite such as Microsoft Office *** cloud-based systems allow users to work together on the same docu-ment stored in a cloud server at once,by which users can effectively collaborate with each ***,there are security concerns unsolved in using cloud *** of the major concerns is the security of data stored in cloud ser-vers,which comes from the fact that data that multiple users are working together cannot be stored in encrypted form because of the dynamic characteristic of cloud *** this paper,we propose a novel mode of operation,DL-ECB,for AES by which we can modify,insert,and delete the ciphertext based on changes in ***,we can use encrypted data in collaborative cloud-based *** demonstrate that the DL-ECB mode can preserve the confidential-ity,integrity,and auditability of data used in collaborative cloud systems from adversaries,we implement and evaluate the prototype of the DL-ECB mode.

Impulsign旨在帮助慈善机构和NGO募集资金,它结合了标牌、透明的OLED屏幕和读卡器,使非政府组织可以向路人展示社交媒体风格的短片("故事"),从而鼓励人们"冲动捐赠"。Impulsign遵循历史悠久的铁路时钟设计隐喻,现在也可以代表"气候危机时钟"。每张卡的捐赠记录都会保存下来,每笔捐赠都会将捐赠者的气候危机时钟设置为1秒钟,作为个人的里程碑,从而激励他们在上下班途中更频繁地捐赠。

关键词：上下班途中气候危机社交媒体捐赠者慈善机构读卡器非政府组织募集资金
