Holographic Data Storage

The holographic memory or holographic data storage is a powerful new technology within the area, storing large-capacity data currently dominated by conventional storage of optical and magnetic data. These devices are based on individual bits stored magnetically or through optical changes on the recording medium’s surface. Consequently holographic memory overcomes these limitations by recording information across the media and storing many images in the same area using different light and angles.

Additionally, while media that stores optical and magnetic data record one bit of information at a time in a linear fashion, holographs are capable of recording and reading millions of bits in parallel, allowing higher data transfer rates than those achieved at through optical storage media.

Recording Data

Holographic memory captures information using an optical interference pattern with dense photosensitive optical material. The light from a single laser divide into two light beams, one for reference and the other for a signal; for its storage, a spatial light modulator is used encoding the data signal. The data obtain to represent in an optical pattern of dark and light pixels due to the crossing between both beams, an optical inference pattern, generating a chemical or physical change in the photosensitive support.

By adjusting the angle of the reference beam, wavelength, or average position. A multitude of holograms (theoretically several thousand) can store on a single carrier. However theoretical limitations of the storage density in this medium are approximately tens of Terabits (1 Tb = 1024 Gigabits / Gb, 1024 Megabits / Mb = 1 Gigabyte / GB) per cubic centimeter. In 2006 InPhase announced a storage capacity of around 500 Gb / in2.

Reading Data

The stored data can read through the reproduction of the same beam used to create the hologram. Meanwhile the light from the reference beam is focus on the photosensitive material, illuminating the appropriate inference pattern. But the Light diffraction is produce in the inference pattern, projecting it onto the reader. The reader is capable of reading the data in parallel, about a million bits at a time. Files on a holographic disk, can access in less than 200 milliseconds.

Holographic memory can provide businesses with powerful archiving information in non-rewritable or single-write formats, thereby preventing overwritten or erased information. However Manufacturers believe that such technology can provide secure data storage for 50 years, over much current media. On the contrary, the technology of data readers evolves rapidly and can extend support by 50 more years.

Sensitivity: scope of modulation of the refractive index produced by exposure units.

The dynamic range: determines how many holograms can multiplex into a single volume of data

The light modulators Space (SLM) are pixel input devices (liquid crystal panels), use to print data store in the lens of the beam.

Holographic Versatile Disc

HVD (stands for Holographic Versatile Disc) or Disk Holographic Versatile is a technology of optical disks. Which increases the storage capacity over optical systems Blu-ray and HD DVD.

A method known as collinear holography is use – in which two lasers, one red and one green-blue, are join into a solitary shaft. However blue-green laser peruses the encoded information. As Interference tops in a holographic layer close to the outside of the disc. The red laser can use to peruse data for servomechanism of a conventional layer CD of aluminum underneath.

It can use to control the position of the read head on the disc, similar to the head. Track and sector information is use on a conventional hard drive (on a CD or DVD this information is insert between the data).

Dichoic Mirror

A dichroic mirror layer is use between the two previous layers, To allow the passage of the red laser and reflect the green-blue laser. This forestalls obstruction because of the refraction of this shaft in the openings of the lower layer procedure. This is as advance, however other holographic stockpiling strategies that either endures obstruction or needed servo data altogether. Making them incompatible with current CD and DVD technology.

What is Cybersecurity?

Cybersecurity, as defined by Definition, is a discipline that is responsible for protecting the integrity and privacy of the information stored in a computer system. However, it is worth clarifying that no technique ensures the inviolability of a system.

It can also define as the combination of steps that a business or individual takes to protect itself, as well as important data, from an attack or unauthorized access. These steps can include several different action items including CISO training. There is a list of what we consider to be essential in the process of solidifying cybersecurity services for you and your business as much as possible.

However, it is important to clarify that cybersecurity is constantly evolving, since thanks to technological advances, new ways of avoiding security controls that one can install always appear. This is why you always to be up to date with the most effective <ahref=”https://technologytimesnow.com/what-is-technology-and-two-methods”>technology, within the levels that your business needs.

Some Steps You has to Take to Protect Your Business

1. Identify your Technology and Key Data.

You must know what “software” is using for tracking important data and on what equipment that “software” store. We recommend that you write down the detailed information of your hardware and software, such as the serial number and any supporting information, to respond in case of an emergency. Another aspect that business owners may fail to protect is on their inventory list. Ideally, inventory should review monthly, and each time a copy is reviewed, it should store in multiple locations.

2. Protect your Data by Implementing Security Measures.

There are more ways that can be used to reduce the risk of having a cyber attack like hiring greatheart.io who are the professionals in preventing any kind of cyber fraudulent activities. Or you can also include creating a copy of all your files, using unique passwords, keeping your software up-to-date, and making sure that a password protects all electronic equipment you have.

3. Detect Threats or Compromised Data.

Pay attention to security-related alerts and train your employees to detect these alerts so that they can be reported to the appropriate personnel immediately afterward. You can dig deeper into security threats by:

• Monitoring network traffic, looking for unusual patterns
• Analyzing the health of your disk for potential storage problems
• Checking and identifying if email filters have blocked alert messages

4. Respond Quickly to Attack.

Create a rapid attack response strategy so that your business can continue operating. Even if it is undergoing a cyber attack. At this time, you will use all the information you copied to a separate device. You will contact the specialist you selected to respond to an incident of this nature; you will also contact legal professionals.

5. Recover by Reevaluating the Technological Security of your Computer.

Consider implementing a more detailed strategic recovery plan than you previously had. Investigate if you have to notify your clients, like other related parties, about the violation of collected data.

The state or federal government dictates the notification requirements in the event of a breach of collected data. Therefore, they should be used as a reference for more information and direction if you find yourself.

What is Assistive Technology?

Assistive services and devices can create an accessible and inclusive environment at work, school, and victim service programs. secondly, Assistive technology is any device, equipment, product, element or service that maintains or increases access, minimizes or eliminates barriers to support and resources, or provides accessibility, autonomy, and self-determination to people who

• Are S / deaf or hard of hearing
• Have a cognitive/developmental disabilit
• Are blind or have vision problems
• Have a physical / motor disability
• It can have a mental or psychiatric disability
• Have multiple disabilities or hidden disabilities

Assistive technology may include mobility devices such as wheelchairs or computer equipment or software facilitating communication and daily activities. For example, an application like Navability helps people who use wheelchairs to navigate the best route.

Other applications, such as TapTapSee (in English), identify objects by photographs for blind people. Speech synthesizers allow a computer to express written text orally, and voice recognition, and gaze-tracking software aid hands-free computer access.

In general terms, any technology could be considered as assistive technology as it expands access.

Assistive Technology and Communication with Survives

Programs must make every effort to ensure the appropriate and safe use of the technology used to communicate with survivors. Here are some ideas:

• Offer accessible and alternative forms of communication for hotlines and permanent services that meet the needs of deaf, hard of hearing, or cognitive or speech disability.
• Post options like a TTY line,  text messaging services, and the voice hotline number.
• When you use TTY, relay services, online chat, or text messaging to communicate, establish a security plan that addresses message interception and device security. Please read more information in our Digital Services Toolkit.
• When using video conferencing technology, work with a deaf advocacy center and qualified video interpreter services.
• Check the equipment frequently to make sure it works properly.
• Make sure intercessors feel comfortable when using assistive technology. Local disability agencies can help programs learn to use the equipment.
• Programs that offer digital services, online information, or access to technology such as computers and WiFi must ensure that they are accessible to all clients and provide software or assistive devices that allow survivors to use them.
• For example, programs may have Web sites they design to allow users to increase the font size, enlarge a Web site, or modify colors.

Accessibility to Hostels and Programs

Programs can use assistive technology to expand accessibility by introducing changes in physical spaces, policies, and practices to better adapt these technologies to survivors’ needs. Likewise, there are some suggestions to get you started:

• • Conduct an accessibility audit of your program and evaluate and address physical and technological accessibility issues.
  • Develop or update policies to modernize or improve accessibility.
  • Include accessible resources and technology in budgets and funding requests.
  • Make sure advocates know-how accessible technology works and its importance to survivors.
  • Incorporate equipment that improves safety and accessibility for survivors.
  • For example, some fire bells and alarms may have flashing lights for deaf people or emit sounds and disable lights for people with epilepsy. Identify where your program can find these tools, keep some in the program, and test them frequently to make sure they work correctly. If you don’t know where and how to find these devices, contact your local Independent Living Center for more information.
  • This also includes accessibility tools on shared computers such as computers and phones, such as how to increase in the size of the text in a web browser, how to increase the volume of a phone, and other built-in accessibility features.
  • Include information on how survivors can make informed decisions about the disclosure of a disability or medical condition within the program.

The Misuse of Assistive Technology

As with any technology, assistive technology can misuse it. Misuse of assistive devices and technology can render survivors unable to perform everyday tasks and pose serious safety risks to a survivor.

Advocates should have a common basic understanding of the potential misuse of these devices and should consult with survivors about their specific concerns and experiences. However, Some examples of ways perpetrators can misuse assistive technology or prevent a survivor from accessing their assistive devices include:

• • • Control or interception of communications. For example, if a survivor uses a computer or telephone to communicate, the abusive person may install spyware or use location tracking services to monitor him.
    • Impersonate the survivor. An abusive person may use a survivor’s broadcast or voice dictation system to pretend to be the survivor. However, request that a protective order or other charges can be drop.
    • Breaking or manipulating assistive technology devices or causing physical harm to the survivor. So that they cannot use their assistive technology device. For example, they break the survivor’s fingers or hands so that he/she cannot write.

Safety and Support Plan for Survivors

Advocates should know how to develop a safety plan with survivors regarding the misuse of assistive technology. This may include:

• • • Help survivors identify safer or more personal communication devices.
    • If identity theft is a concern, intercessors and survivors can agree and use code phrases known only to the survivor to make sure it is him/her.
    • Assist survivors in finding replacements or obtaining repairs for technological devices damaged by an abusive person.

Include assistive technology plans in cases where survivors seek services or are moving.
