the previous access controlsystems have high computation withthe persons biometric information, cryptography, and so on. However, the embedding and extraction process of proposed scheme is simple and efficiency because of this paper is proposed by using data hiding and the visual secret sharing. When the user try to the access system, it is provided to the triple authentication of user that the extracted QR code image and the secret image are verified withthe secret key of user.

Wooden furniture of organic shapes was mostly handmade in the past, each piece was almost unique, since the manufacturing processes did notiallow repeatability and larger quantity production of the same products. Today, modern 3D modelling software leads to completely different prospective in wooden furniture design and production. It enables modelling of any kind of shape, based on ideas, natural shapes, even 3D scanned existing shapes, etc. Furthermore, prototypes can be 3D printed. this enables that visual presentation of designed form is made in real. Based on the printed forms virtual models can be improved leading to the final sophisticated model. Additionally, during design process the best construction details can be made to improve material efficiency and manufacturing time. Final product can be than made on CNC machines, enabling reproduction of the same product of desired shape in chosen quantities.

Recent research has focused on the fabrication freedom of 3D printing to not only create conceptual models but final end-use products as well. By democratizing the manufacturing process, products will inevitably be fabricated locally and with unit-level customization. For 3D printed end-use products to be profoundly meaningful, the fabrication technologies will be required to enhance the structures with additional features such as electromechanical content. In the last decade, several research groups have reported embedding electronic components and electrical interconnect into 3D printed structures during process interruptions. However, to date there appears to be an absence of fabricated devices with electromechanical functionality in which moving parts with electronic control have been created within a single Additive Manufacturing (AM) build sequence. Moreover, previously reported 3D printed electronics were limited by the use of conductive inks, which serve as electrical interconnect and are commonly known for inadequate conductivity. this paper describes the fabrication of a high current (>1 amp) electromechanical device through a single hybrid AM build sequence using a uPrint Plus, a relatively low cost 3D. Additionally, a novel integrated process for embedding high performance conductors directly into the thermoplastic FDM substrate is demonstrated. By avoiding low conductivity inks, high power electromechanical applications are enabled such as 3D printed robotics, UAVs and biomedical devices.
