## Title
Webcam privacy shield

## Abstract

A webcam privacy shield is magnetically attached to a bezel of an electronic display that includes a webcam. The webcam privacy shield is positioned in either a shielded position where light is blocked from entering the lens of the webcam by positioning an opaque portion of the webcam privacy shield over the lens of the webcam, or an operating position where light is allowed to enter the lens of the webcam by positioning a transparent portion of the webcam privacy shield of the lens of the webcam. Sliding the webcam privacy shield between the shielded position and the operating position allows the user to selectively maintain their privacy from the webcam, or use the webcam.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims benefit under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61/843,338 filed on Jul. 6, 2013 the entire contents of which are hereby incorporated by reference for any and all purposes.


BACKGROUND
1. Technical Field
The present subject matter relates to computer webcams. More specifically, it relates to a privacy shield for a webcam.
2. Description of Related Art
Over the last 10-15 years, webcams have become an increasingly popular peripheral for personal computers. At first, webcams were stand-alone devices with an analog video connection to the computer, but gradually, a USB interface became the defacto standard for the interface to a stand-alone webcam. A common usage model was to plug the webcam into the computer if an application that would use the webcam was going to be used, such as a video chat application. Once the user was done with using the application, the webcam could be unplugged and put away. Some webcams included a privacy shield, such as a mechanical shutter, that allowed the lens to be covered if the user wanted to block the view from the webcam for privacy reasons.
Various types of malware have also become increasingly common over the last 10-15 years. Malware may take many forms, including, but not limited to, computer viruses, Trojan horse software, spyware, ad-ware, or misbehaving applications. In some cases, malware has been designed to hijack a webcam and send video from the webcam to another computer over a network, which might be in the next room, across the country, or anywhere in the world, if the webcam is coupled to an internet connected device.
Recently, webcams have become nearly standard equipment on notebook computers, as well as tablets and smartphones. Most webcams on notebook computers, tablets, and smartphones do not include a privacy shield. This may be due to market demands for thin form factors or other reasons. If no privacy shield is included, malware may be able to hijack the webcam without the user's permission or knowledge, which may allow the malware to spy on the user, invading their privacy. Still and/or video images acquired by the malware may be embarrassing, or even dangerous, to the user. In some cases, images from the malware have been posted to social media sites, embarrassing the subject of the images and leading to potential damage to the subject's social and business relationships. Criminals may even attempt to use such images to blackmail the subject. Users of traditional webcams can avert hijacking of the webcam by simply unplugging the webcam, but if the webcam is built into the device, and the device needs to be left on for some reason, this is not possible. This leaves people that may engage in activities that they wish to keep private vulnerable to malware which may hijack the webcam of a nearby device.

DETAILED DESCRIPTION
In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures and components have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present concepts. A number of descriptive terms and phrases are used in describing the various embodiments of this disclosure. These descriptive terms and phrases are used to convey a generally agreed upon meaning to those skilled in the art unless a different definition is given in this specification. Some descriptive terms and phrases are presented in the following paragraphs for clarity.
Magnetic material is a material that may be attracted to a magnet. Magnetic material may or may not remain magnetized without an external magnetic field. Examples of magnetic material include a magnet, steel, or other ferromagnetic materials.
A magnet is a magnetic material that generates a magnetic field, or is magnetized, even if the magnet is not being subjected to an external magnetic field. A magnet may also be referred to as a permanent magnet.
Ferromagnetic material, for the purposes of this disclosure, including the claims, refers to a magnetic material that does not generate a significant magnetic field of its own, or is not magnetized, without the presence of an external magnetic field. Ferromagnetic materials are attracted to a magnet. Ferromagnetic materials may include iron, nickel, cobalt, and many of their alloys, such as many steel alloys, as well as some compounds of rare earth metals. For the purposes of this disclosure, ferromagnetic materials include ferrimagnetic materials that are attracted to a magnet.
A webcam is a camera capable of taking still images, video images, or both, that is coupled to a computer. For the purposes of this disclosure, including the claims, the words camera, and webcam may be considered to be synonyms. Any type of camera may be a webcam, including, but not limited to a video camera, a still camera, a cell phone camera, a mobile device camera including, but not limited to, a backward facing camera, a thermal imager, a CCD device, a three-dimensional camera, or any other type of image capture apparatus that may allow the capture of image data and provide it to an electronic system. In some embodiments, a webcam may be integrated into an electronic system, such as, but not limited to, a notebook computer, a tablet, a smart phone, or a separate electronic display.
Many electronic systems now include an integrated camera, such as a webcam. While in the past, it was common for webcams to include a mechanical shutter to allow a user to block light from entering the lens, many modern systems do not include a mechanical shutter on their integrated webcams. This may create a risk, or at least a perceived risk, of a lack of privacy, especially given highly publicized incidents where a webcam has been used to spy on an individual. The rise of various types of malware have increased the need to be able to mechanically shield a webcam in such a way that it cannot be overridden by malware and where it is easy to verify that the webcam is indeed shielded and not able to capture any images of its surroundings.
Some electronic systems that include an integrated webcam also include magnets in the same general proximity of the webcam, such as in the bezel of a display. The magnets may be included for a variety of reasons, such as to provide a force to keep a notebook computer closed, to detect if a lid of a notebook computer has been closed, or to detect if a cover has been placed over the display. The inventors realized that these same magnets may also be used to hold a webcam privacy shield in position on the bezel of the display. The webcam privacy shield may be designed to make it obvious to the user whether or not the webcam is shielded, or whether the webcam is operable and able to capture images of the surrounding environment.
In embodiments, the webcam privacy shield is a thin, elongate, member with a hole, or transparent portion, that can be positioned over the lens of the webcam by the user to allow the webcam to operate normally. If the user wished to shield the webcam, the webcam privacy shield may simply be slid to one side, covering the lens of the webcam with an opaque portion of the webcam privacy shield. A user can then easily tell whether or not the webcam has been blocked by glancing at the computer and seeing whether the lens of the webcam is visible. To use the webcam again, the user simply slides the webcam privacy shield to position the hole, or transparent portion, over the lens of the webcam again.
Because the location of magnets may vary between different electronic systems, the configuration and exact dimensions of the webcam privacy shield may be different for different systems. By locating magnetic material of the webcam privacy shield at specific locations with respect to opaque portions and transparent portions of the webcam privacy shield, the webcam privacy shield may be held in place by the magnets in the electronic system in either a shielded position or an operating position. In some cases, however, a webcam privacy shield may be designed to accommodate multiple models of electronic systems. For example, in at least one popular family of notebook computers, the Apple® MacBook® line of computer, including many models of the MacBook Air® and MacBook Pro®, four magnets are integrated into the top bezel of the display that forms the lid of the notebook computer. These models also integrate a webcam into the top bezel of the display. The locations of the four magnets with respect to the webcam are substantially the same across several different models, or at least close enough to being the same that a single version of the webcam privacy shield may be used across most, if not all, models of the MacBook product line.
The webcam privacy shield may be constructed using any type of material as its base material, although some embodiments may be constructed from a sheet of ferromagnetic material, and others may be constructed using a plastic base material with some magnetic material embedded in, or attached to, the plastic base material. A transparent portion of the webcam privacy shield may be a hole in the base material, or may be formed from a piece of transparent material. Some embodiments of the webcam privacy shield may also include non-scratch material on the back side of the webcam privacy shield, to minimize scratching of the bezel as the webcam privacy shield is slid on the surface of the bezel. In some embodiments, the non-scratch material may also reduce friction as the webcam privacy shield is slid.
Many different types of ferromagnetic material may be used for various embodiments. Some embodiments may use steel that is 0.05 millimeter (mm), 0.20 mm, 0.25 mm, 0.004 inch (′′) (or 0.102 mm), 0.005′′ (0.127 mm), 0.006′′ (0.152 mm), 0.007′′ (0.178 mm), or 0.008′′ (0.203 mm) thick. Some embodiments may use a cold rolled steel. Other embodiments may use 400 series stainless steel, such as 410, 416, 420, 520, Or 440C stainless steel. Some embodiments may choose a ferromagnetic material having a hardness of Rockwell C48 or higher. In at least one embodiment, blue-finished and polished 1095 spring steel may be used. Other embodiments may use low carbon steel shim stock, general purpose low-carbon steel foil, or economy grade 430 stainless steel foil.
The webcam privacy shield may be thin enough to allow a notebook computer to be closed with the webcam privacy shield in place. The webcam privacy shield may be compatible with other accessories commonly used on a notebook computer, such as a 3MTM Privacy Filter. The webcam privacy shield may magnetically attach to the bezel over the top of the Privacy Filter, as the Privacy Filter does not block the magnetic fields. The webcam privacy shield may be thin enough to allow a notebook computer to be closed with both the Privacy Filter and the webcam privacy shield in place.
The webcam privacy shield may be made in any color to match the design of the electronic device or to appeal to a user. Example colors may include black, white, or silver to match the color of a bezel of a target electronic display, or blue, pink, red, green, or other popular color. The webcam privacy shield may also be used for advertising or promotion and have an advertisement, company logo, or other promotional information printed, engraved, or otherwise attached to the visible side of the webcam privacy shield. The webcam privacy shield may then be used as a promotional item, perhaps even be distributed at no cost to a user, to promote the product, service, or company shown on the front.
Reference now is made in detail to the examples illustrated in the accompanying drawings and discussed below.
FIG. 1A is a drawing of a first embodiment of a webcam privacy shield 120. The 1st webcam privacy shield 120 may be useable for some models of an Apple MacBook Pro notebook computer, and may be usable for other electronic systems as well. The 1st webcam privacy shield 120 may be cut from a thin sheet of opaque magnetic material, which may be a ferromagnetic material, forming a thin, elongate, member, or strip of ferromagnetic material. Thin, as used herein and tin the claims, may be defined relative to the width of the strip. Material may be referred to as thin if the thickness is less than about 20% of the width of the strip. Various portions of the strip of ferromagnetic material may act as an opaque portion of the thin, elongate, member, and a magnetic portion of the thin, elongate, member. In various embodiments similar to the 1st webcam privacy shield 120, the ferromagnetic material may be no more than 1 mm thick, and may be steel between 0.05 mm and 0.30 mm thick in some embodiments. In at least some embodiments, the steel may be stainless steel or spring steel that is between 0.10 mm and 0.25 mm.
The 1st webcam privacy shield 120 may be formed as a thin, elongate, member having a total length of about 250 mm and a constant width of about 10 mm. The ends may have radiused corners with a radius of about 5 mm, although other embodiments may use different radii. Other similar embodiments may have different lengths and widths, with the width varying along the length in some embodiments. Some embodiments may have a length that does not exceed 400 mm with a width that does not exceed 40 mm. Some embodiments may have a length between 180 mm and 300 mm with a width between 8 and 20 mm, while some embodiments may have a length between 230 mm and 280 mm with a width between 9 and 15 mm.
The 1st webcam privacy shield 120 includes a hole 122 cut through the thin, elongate, member, or strip, to create a transparent portion. The size and position of the hole 122 may vary between embodiments, but the hole 122 of the 1st webcam privacy shield 120 is about 16 mm long and about 7 mm wide with radiused corners and centered in the width of the thin, elongate member. The hole 122 may not be centered in the length of the 1st webcam privacy shield in at least some embodiments, with one edge of the hole 122 located about 110 mm from one end of the thin, elongate, member, and the opposite edge of the hole 122 located about 124 mm from the opposite end of the thin elongate member. In various embodiments, the hole may be at least about 10 square millimeters (mm2) in size and may be located no closer than about 70 mm from either end of the thin, elongate, member. The hole may have any shape, but may be a circle, an oval, an ellipse, a rectangle, or a rectangle with radiused corners in some embodiments. In some embodiments, the hole may be between 5 mm and 15 mm wide and between 5 mm and 25 mm long, and in some embodiments, the hole may be between 10 mm and 20 mm long, with a width that is at least 6 mm but no wider than 2 mm less than the maximum width of the thin, elongate member, to leave at least 1 mm of material on either side of the hole. In some embodiments, an edge of the hole may be located at least 80 mm from a first end of the thin, elongate, member, and an opposite end of the hole may be located at least 90 mm from an opposite end of the thin, elongate, member, but in some embodiments, the hole may be located no closer than 100 mm from either end of the thin, elongate, member.
FIGS. 1B and 1C depict an electronic system 100 with a first embodiment of a webcam privacy shield 120 in an unshielded and shielded position, respectively. The electronic system 100 includes a notebook computer 110. Other embodiments may be suited for use on other types of electronic systems, such as a stand-alone electronic display, a tablet, or a smart phone. The notebook computer 110 includes an electronic display 111 with a bezel 112. A light emitting diode (LED) 113 may be included in some electronic systems next to a webcam 114 that is integrated into the bezel 112. The LED 113 may be used as an illumination source and/or as an activity indicator, depending on the electronic system. At least one magnetic area may be integrated into the bezel 112 of the electronic display 111. The magnetic areas may be one or more permanent magnets embedded into the bezel 112, and/or ferromagnetic material used to construct the bezel 112, embedded in the bezel 112, or attached to the bezel 112.
The webcam privacy shield 120 may be magnetically attached to the bezel 112. The webcam privacy shield 120 may be constructed as a thin, elongate, member with a magnetic portion, and an opaque portion. The webcam privacy shield 120 may be positioned in an operating position as shown in FIG. 1B, or in a shielded position as shown in FIG. 1C. If the webcam privacy shield 120 is positioned in the operating position, a hole 122 may be positioned to expose the lens of the webcam 114 and to allow the webcam 114 to receive light and capture images of its surrounding environment. The LED 113 may also be exposed through the hole 122 if the webcam privacy shield 120 is in the operating position. If the webcam privacy shield 120 is positioned in the shielded position, an opaque portion of the webcam privacy shield 120 may be positioned to cover the lens of the webcam 114 and to block light from entering the lens of the webcam 114, thereby protecting the visual privacy of any individuals in the surrounding area. The LED 113 may also be covered by the opaque portion of the webcam privacy shield 120 if the webcam privacy shield 120 is in the shielded position. The webcam privacy shield 120 may be held in either the operating position or the shielded position by a magnetic attraction between the at least one magnetic area of the bezel and the magnetic portion of the thin elongate member.
The notebook computer 110 also includes a base unit 115 with a keyboard 116. The base unit 115 may include a processor and memory, although some embodiments may include the processor and memory behind the display 111. The electronic display 111 is hingedly coupled to the base unit 115 to fold over the keyboard 116. The thin, elongate, member is thin enough to allow the electronic display 111 to fully close over the keyboard 116 with the thin, elongate, member in the either shielded or operating position. If a latching mechanism is included in the notebook computer, the electronic display 111 is deemed to be fully closed if the latching mechanism is able to hold the electronic display 111 folded over the keyboard 116. Latching mechanism is intended broadly, and may be a mechanical latch, an electric-mechanical latch, a magnetic force, spring tension, or friction in the hinge, among other latching mechanisms.
FIGS. 2A and 2B depict a second embodiment of a webcam privacy shield 220 in positions to respectively uncover 200A and cover 200B a webcam 214 on a bezel 212 of an electronic display 211. The electronic display 211 may be a part of an electronic system, such as a notebook computer, and may more specifically represent a top portion of the lid of a notebook computer of the Apple MacBook family.
The 2nd webcam privacy shield 220 is constructed from a thin strip of steel to form a thin, elongate member. The steel may be of any suitable thickness but may be between about 0.05 mm and 0.25 mm in some embodiments. In at least one embodiment, the steel may be blue-finished and polished 1095 spring steel between 0.100 mm and 0.130 mm thick, such as 0.004′′ or 0.005′′ stock. This is a magnetic stainless steel alloy that may be able to tolerate being bent up to a certain point, without creating a permanent bend or crease in the material. In some embodiments, the spring steel may be painted to provide an attractive appearance.
The 2nd webcam privacy shield 220 has an overall length of about 246 mm, although other embodiments may have different lengths. The 2nd webcam privacy shield 220 has a varying width over its length. The width of the strip at the first end is about equal to the width of the strip at the opposite end, and the width of the strip at the hole is wider than the width of the strip at the first end. In the 2nd webcam privacy shield 220, the ends have a width of about 10 mm, and the width at the hole 222 is about 12 mm. The first end of the strip and the second end of the strip have radiused corners, which have a radius of about 5 mm in the 2nd webcam privacy shield 220.
The 2nd webcam privacy shield 220 includes a hole 222 cut through the strip to create a transparent portion. The hole 222 is about 16 mm long and about 9 mm wide with corners having about a 4.5 mm radius, although other embodiments may have different sized and/or shaped holes. The hole 222 is about centered in the width of the strip and is located about 108 mm from one end of the strip, and about 122 mm from the other end of the strip. Other embodiments may locate the hole at a different position on the strip.
Several members of the MacBook family include four magnets 216-219 embedded in the bezel 212 of their display 211. At least the MacBook Pro 13′′ Unibody, MacBook Pro 15′′ Unibody, MacBook Pro 17′′ Unibody, MacBook Pro 13′′ with Retina® Display, MacBook Pro 15′′ with Retina Display, MacBook Air 11′′, MacBook Air 13′′, the new MacBook Air 11′′ and the new MacBook Air 13′′ include the four magnets 216-219 in the same horizontal location with respect to the integrated webcam 214, although other past or future models in the Apple MacBook family may have magnets in the same or different locations, or may even remove the magnets from the bezel. Other products, such as stand-alone displays from Apple, or electronic systems from other companies, may or may not have a similar arrangement of a webcam and magnets on a bezel of a display.
The first magnet 217 may be located about 85 mm to the left of the webcam 214. The second magnet 218 may be located about 95 mm to the right of the webcam 214. The third magnet 216 may be located about 135 mm to the left of the webcam 214, and the fourth magnet 219 may be located about 135 mm to the right of the webcam 214. The vertical location of the webcam 214 may vary somewhat between MacBook models. In many MacBook models, the center of the webcam 214 is approximately at the same vertical position as the center of the magnets 216-219. But in the new MacBook Air models, the center of the webcam 214 may be about 2.5 mm lower than the center of the magnets 216-219. The thicker center section of the thin, elongate member allows for a wider hole 222, which can accommodate different vertical positions of the webcam 214. So the electronic system, which has at least one magnetic area, includes a first magnet 217 integrated into the bezel 212 of the electronic display 211 on a side of the webcam 214 opposite of a second magnet 218. The at least one magnetic area includes at least the first magnet and the second magnet.
The 2nd webcam privacy shield 220 may be constructed as a the thin, elongate, member from a steel sheet with a hole 222 through the steel sheet. The magnetic portion and the opaque portion of the thin, elongate, member may be formed by the steel sheet. A transparent portion of the thin elongate member may be formed by the hole 222.
The 2nd webcam privacy shield 220, or thin, elongate, member, may be slideable to an operating position 200A to place the hole 222 over the lens of the webcam 214. In the operating position 200A, the 2nd webcam privacy shield may engage with the first magnet 217 and the second magnet 218, and the thin, elongate, member may be held in the operating position 220A by the magnetic attraction between the at least one magnetic area 217-218, and the steel of the 2nd webcam privacy shield 220.
The 2nd webcam privacy shield 220, or thin, elongate, member, may be slideable to shielded position 200B to place an opaque portion of the thin, elongate, member over the lens of the webcam 214. In the shielded position 200B, the 2nd webcam privacy shield may engage with at least the first magnet 217 and the second magnet 218, and the thin, elongate, member may be held in the operating position 220A by the magnetic attraction between the at least one magnetic area 217-218, and the steel sheet. The thin, elongate, member may also engage with the third magnet 216 in the shielded position 200B. Alternatively, 2nd webcam privacy shield 200 may be slid to the right, to cover the lens of the webcam 214 with a different opaque portion of the thin, elongate, member to create an alternative shielded position (not shown). In the alternative shielded position, the thin, elongate, member may engage with the fourth magnet 219, instead of the third magnet 216.
FIGS. 3A and 3B depict a third embodiment of a webcam privacy shield 320 in positions to respectively uncover 300A and cover 300B a webcam 314 on a bezel 312 of an electronic display 311. The electronic display 311 may be a part of an electronic system which may be a model in the MacBook family or may be some other electronic system. The electronic system may include a first magnet 317, and a second magnet 318, with at least one magnet on each side of the webcam 314. Some embodiments of a bezel 312 suitable for use with the 3rd webcam privacy shield 320 may include additional magnets in the bezel 312.
The 3rd webcam privacy shield may be constructed from a thin strip of ferromagnetic material with a hole 322. The 3rd webcam privacy shield 320 may engage with at least two magnets 317-318 embedded in an electronic device display bezel 312. The 3rd webcam privacy shield 320 may be similar to the 1st webcam privacy shield 120 or 2nd webcam privacy shield 220, but the length of the 3rd webcam privacy shield 320 may be determined by measuring the distance from the first magnet 317 to the second magnet 318 and adding at least the length of the hole 322 to determine the length of the 3rd webcam privacy shield 320. So if the hole is 15 mm long, and the distance from the webcam 314 to each of the two magnets 317-318 is 100 mm, the 3rd webcam privacy shield may be determined to be at least 215 mm long.
In a shielded position 300B, the 3rd webcam privacy shield 320 may cover the lens of the webcam 314 embedded in the electronic device display bezel 312 with an opaque portion to block light from the surrounding environment to enter the lens of the webcam 314. In the operating position 300A, the 3rd webcam privacy shield 320 may position the hole 322 over the lens of the webcam 314 to allow light from the surrounding environment to enter the lens of the webcam 314 embedded in the electronic device display bezel 312.
The hole 322 may be formed so that the 3rd webcam privacy shield is able to engage with both the first magnet 317 and the second magnet 318 in both the shielded position 300B and the operating position 300A. The 3rd webcam privacy shield is slideable between the operating position 300A and the shielded position 300B.
FIGS. 4A and 4B depict a fourth embodiment of a webcam privacy shield 420 in positions to respectively uncover 400A and cover 400B a webcam 414 on a bezel 412 of an electronic display 411. The electronic display 411 may be a part of an electronic system, such as a notebook computer, and includes a pad 416 with may extend from the bezel 412. The bezel 412 also includes at least one magnet 417, although other embodiments suitable for the 4th webcam privacy shield 420 may include additional magnets in the bezel 412.
The 4th webcam privacy shield 420 may selectively block light from entering a camera lens, as do the other embodiments of a webcam privacy shield described herein. The 4th webcam privacy shield 420 may be constructed as a thin, elongate, member from sheet steel. The sheet steel may function as an opaque portion and a magnetic portion of the thin elongate member. A hole 422 may be formed in one end of the 4th webcam privacy shield 420 to act as a transparent portion. If the 4th webcam privacy shield 420 is positioned by a magnetic attraction of the magnetic portion in the shielded position 400B, with an opaque portion over the lens of the webcam 414, the 4th webcam privacy shield 420 blocks light from entering the lens of the webcam 414. If the 4th webcam privacy shield 420 is held by a magnetic attraction of the magnetic portion in the operating position 400A, with the transparent portion over the lens of the webcam 414, the 4th webcam privacy shield 420 allows light to enter the lens of the webcam 414.
The 4th webcam privacy shield 420 may only engage with a single magnet 417 to hold the 4th webcam privacy shield 420 in the operating position 400A or the shielded position 400B. In some embodiments, the pad 416 may act as a brace, to keep the 4th webcam privacy shield 420 from rotating about the magnet 417 in the operating position 400A, and/or the shielded position 400B.
FIGS. 5A and 5B depict a fifth embodiment of a webcam privacy shield 520 in positions to respectively uncover 400A and cover a webcam 500B on a bezel 512 of an electronic display 511. The 5th webcam privacy shield 520 may be formed from a thin plastic strip. The 5th webcam privacy shield 520 may be a thin elongate member with a transparent portion 522, an opaque portion 524, and magnetic portions 523-526. Note that one or more of the magnetic portions 524, 525 may also be an opaque portion. The transparent portion 522 may be made from a transparent plastic portion of the plastic strip, although other embodiments may cut a hole to form the transparent portion 522. If the transparent plastic portion is placed over the lens of a webcam, the lens of the webcam is deemed to be uncovered, for the purposes of this disclosure and claims. In some embodiments, the opaque portion is made from an opaque coating on a portion of the plastic strip or opaque plastic. In some embodiments, the opaque portion may be at least a part of the magnetic portion.
Depending on the embodiment, a magnetic portion may be formed using a magnet or a ferromagnetic material, where the magnetic material is embedded in, or attached to, the plastic strip to form the magnetic portion. One magnetic portion may be formed using a magnet 523 attached to, or embedded in, the plastic strip of the 5th webcam privacy shield 520. The magnet 523 may be oriented so that it is attracted to the first magnet 516 embedded in the bezel 512. A first magnetic portion 524, and a second magnetic portion 525, which may also be opaque portions, may be formed by attaching or embedding ferromagnetic material in the plastic strip.

The second magnetic portion 525 is attracted to the second magnet 517 in the bezel 512 to help hold the 5th webcam privacy shield 520 to the bezel 512. The magnet 523 in the 5th webcam privacy shield 520 may be more strongly attracted to the first magnet 516 in the bezel 512. This strong attraction may help to position the 5th webcam privacy shield 520 in the shielded position, providing a positive feel for the user to know that the 5th webcam privacy shield 520 is positioned properly.
The 5th webcam privacy shield 520 may also be suitable for use in electronic systems where the display has a bezel with areas of ferromagnetic material on either side of the webcam. The magnets 523, 526 in the 5th webcam privacy shield 520 may be attracted to the ferromagnetic material to allow the 5th webcam privacy shield to be positioned in either an operating position to allow light to enter the lens of the webcam, or a shielded position to block light from entering the lens of the webcam.
In some embodiments of a webcam privacy shield that are similar to the 5th webcam privacy shield 520, the magnets 523, 526 may be omitted. Or the magnet 523 may be considered to be a part of the first magnetic portion 524 and the magnet 526 may be considered to be a part of the second magnetic portion 525. So the shielded position 500B of the thin, elongate, member on a bezel 512 of an electronic display 511 positions the opaque portion 524 over the camera lens, or lens of the webcam 514, and an operating position 500A of the thin, elongate, member on the bezel 512 positions the transparent portion 522 over the camera lens, or lens of the webcam 514. The first magnetic portion 524, engages with a first magnetic area 516 of the bezel 512 in both the shielded position 500B and operating position 500A, and the second magnetic portion 525, engages with a second magnetic area 517 of the bezel 512 in both the shielded position 500B and operating position 500A. The magnetic attraction between the first magnetic area 516 and the first magnetic portion 524, and the magnetic attraction between the second magnetic area 517 and the second magnetic portion 525 holds the thin, elongate, member statically in either the shielded position 500B or operating position 500A.
