Digital Watermarking Based on DCT Transform
A Survey of Digital Watermarking Technologies Lin Liu [email protected] Abstract: This report introduces the basic concepts in digital watermarking. Common watermarking technologies are reviewed. Some experiment results are provided as well. Index Terms: Digital watermarking, copyright protection 1. INTRODUCTION During the past decade, with the development of information digitalization and internet, digital media increasingly predominate over traditional analog media. However, as one of the concomitant side-effects, it is also becoming easier for some individual or group to copy and transmit digital products without the permission of the owner. The digital watermark is then introduced to solve this problem. Covering many subjects such as signal processing, communication theory and Encryption, the research in digital watermark is to provide copyright protection to digital products, and to prevent and track illegal copying and transmission of them. Watermarking is embedding information, which is able to show the ownership or track copyright intrusion, into the digital image, video or audio. Its purpose determines that the watermark should be indivisible and robust to common processing and attack. Currently the digital watermarking technologies can be divided into two categories by the embedding position——spatial domain and transform domain watermark. Spatial domain techniques developed earlier and is easier to implement, but is limited in robustness, while transform domain techniques, which embed watermark in the host’s transform domain, is more sophisticated and robust. With the development of digital watermarking, spatial techniques, due to their weakness in robustness, are generally abandoned, and frequency algorithm based on DCT or DWT becomes the research focus. Another tendency in watermarking is blind extraction, which means the host is not need when extracting the watermark; otherwise it is hard to avoid the multiple claims of ownerships. -
DIGITAL Media Players Have MEDIA Evolved to Provide PLAYERS a Wide Range of Applications and Uses
2011-2012 Texas 4-H Study Guide - Additional Resources DigitalDIGITAL media players have MEDIA evolved to provide PLAYERS a wide range of applications and uses. They come in a range of shapes and sizes, use different types of memory, and support a variety of file formats. In addition, digital media players interface differently with computers as well as the user. Consideration of these variables is the key in selecting the best digital media player. In this case, one size does not fit all. This guide is intended to provide you, the consumer, with information that will assist you in making the best choice. Key Terms • Digital Media Player – a portable consumer electronic device that is capable of storing and playing digital media. The data is typically stored on a hard drive, microdrive, or flash memory. • Data – information that may take the form of audio, music, images, video, photos, and other types of computer files that are stored electronically in order to be recalled by a digital media player or computer • Flash Memory – a memory chip that stores data and is solid-state (no moving parts) which makes it much less likely to fail. It is generally very small (postage stamp) making it lightweight and requires very little power. • Hard Drive – a type of data storage consisting of a collection of spinning platters and a roving head that reads data that is magnetically imprinted on the platters. They hold large amounts of data useful in storing large quantities of music, video, audio, photos, files, and other data. • Audio Format – the file format in which music or audio is available for use on the digital media player. -

Informed Consent for Telemedicine Services
INFORMED CONSENT FOR TELEMEDICINE SERVICES Patient Name: Date of Birth: Address: City: State: Zip: Date Consent Discussed: INTRODUCTION Telemedicine is a subset of telehealth services that uses online, interactive videoconference software to provide medical services from a distance. Private insurance companies in CT and Medicaid temporarily, are required by law to cover telemedicine health services. Telemedicine does not include the use of fax, audio-only telephone, e-mail, or videotelephony products such as FaceTime and Skype. Telemedicine involves the use of electronic communications to enable health care providers at different locations to share individual patient medical information for the purpose of improving patient care. Providers may include primary care practitioners, specialists, and/or subspecialists. The information may be used for diagnosis, therapy, follow‐up and/or education, and may include any of the following: • Patient medical records • Medical images • Live two‐way audio and video • Output data used will incorporate network and software security protocols to protect the confidentiality of patient identification to safeguard the data and to ensure its integrity against intentional or unintentional corruption EXPECTED BENEFITS • Improved access to medical care by enabling a patient to remain in his/her home (or at a remote site) while the physician obtains test results and consults from healthcare practitioners at distant/other sites • More efficient medical evaluation and management POSSIBLE RISKS As with any medical procedure, there are potential risks associated with the use of telemedicine. These risks include, but may not be limited to: • In rare cases, information transmitted may not be sufficient (e.g. poor resolution of images) to allow for appropriate medical decision making by the provider and consultant(s) | 945 Main Street Suite 205, Manchester, CT 06040 | p 860.553.3020 | f 860.553.3232 | www.emmaushealthllc.com | Page 1 of 2 Rev. -
