# Novel Algorithm for Multi-Time Data Implantation in a Special Cyber-Manufacturing Architecture
## 1 Introduction  
Cyber manufacturing is one of the most influential branches of the physical cyber system. Typically, a cyber-manufacturing system focuses on the architecture of the devices used in cyber systems, their data acquisition, retrieval and processing methods, the functional efficiency and security features of data and devices [1]. At the same time, it deals with related engineering and technological aspects of the devices to make them good-looking, easy to use and strong. Very commonly used cyber devices are smart watches, healthcare and assistance devices of disabled and elderly people [2]. With the advancement in industry and technology, those devices have started to stand out in terms of their functionality. In today's world, no one doubts that, in near future, a small device will provide us with multiple services, e.g., we could add our own security, day-to-day work, accounting, asset management, etc. Then, body-worn devices will obtain a different dimension. These devices will be widely used to simplify our day-to-day operations and increase security [2]. Certainly, these devices will include healthcare services, as well. Current healthcare devices are capable of storing several pieces of casual information about the people who wear them. Some devices may update a user's information to a limited extend through a set of device-implanted sensors. However, future healthcare devices will show many surprises that are unimaginable compared to the present time. They will be able to perform many physical and pathological experiments on the human body automatically. These devices will automatically start communicating with the designated doctors or any healthcare provider to receive suggestions and consultations. It will not be surprising if a robotic device takes its owner to the doctor or hospital if it senses the deteriorated health condition of the owner. Although we have started to see similar applications in a short range, there are still questions about their capability and the quality of their skills. That limitation is mainly due to the small size and low-cost demand of such devices. However, we expect better services from them by making them capable of processing and storing huge amounts of information. The healthcare devices will store demographic, pathological, historical and other data of the owner in their memory. This information will be updated regularly. In that case, if we preserve the historical data, at some point in time, that data will become larger, especially for old patients and chronic diseases. It could even be larger than the memory capacity of the device. Again, the information stored on the device will be threatened because the device will be connected to the cyber world and its information can easily be stolen if we store plane data in them. Hence, processing data to a secured format is essential. Moreover, failure to provide data protection will also hamper the cyber-manufacturing process. Therefore, in these days, the security breach on the information will be a big obstacle in the way of obtaining good service. If we do not work now on the security architecture of the cyber-manufacturing world, the cyber-manufacturing method, especially on wearable healthcare devices, will not be implemented [3]. Consequently, we have to look at three things--(i) a simple architecture for the device, (ii) its information management and (iii) information security. Hence, in this article, we place an emphasis on developing an architecture for future healthcare devices and an efficient algorithm for their data management and security. Our primary target is to design a simple but effective architecture. We first assume that the intended wearable cyber device is equipped with the necessary sensors to collect and process human health information as well as to store them. The sensors are connected to a memory unit and a signalling unit through the processing unit of the device. The memory unit consists of two parts--a restricted part and a reusable part.
